not long at all, but i dont see why that should be held against me, when there isnt a race on im reading about races of the past etc, which i think more pepople should do as they might realise that prost>senna 

Nothings being held against you, my meaning was that firsthand experience means more than reading or whatching reruns or short clips. How many times do you hear "Oh dude I read about that and it was bogus" and then you can say "Well frankly I witnessed it firsthand and your just a tad off" or "this is really what/how it happened". 
No i agree, and in thirty years if F1s still going i wouldnt and dont plan to hold it against those who have only watched since 2025 when mr.roboto burst on the sscene driving the ferrari cyborg-4550. But still i find it hard to take that Prost is mentioned only really as a good driver and one of the 80's greats, he was amazing! and from what ive read, even through the Senna biased stuff, Prost takes the best ever for me. I mean in 1988 he got more points then Senna but the points system only classified your best 11 results, in which Senna had more wins.
Having watched them race at the time, I don't think the two are even comparable so it depends on what you are looking for to decide on what you class as criteria to be the best.
If you look for pure intelligence and the ability to plan and make contingencies, strategy, the ability to look after a car whilst still being faster than 95% of the field most of the time then Prost is your man.
If on the other hand you're looking for pure out and out speed and driving on instinct with the ability to not just be quick, but to utterly dominate everyone on his day to the ridiculous extent (pole by over 2 seconds to second place??), then it is unquestionably Senna - that's not even something that can be debated.
I love watching Prost drive and still watch his every race in the Andros Trophee - interestingly enough he could be this weekend about to fall foul of the same situation as in '88 with Senna. He's currently leading the championship by 3 points from Dayraut in second place, but at the end of the season for the championship, each driver's worst weekend (2 races!) are written off. Prost has been consistently good, so Dayraut's worst is of course worse than Prosts meaning even though Prost leads the championship technically now, he will be behind after the weekend unless he wins at least one of the races... history repeats itself....
totally comparable, correct me if im wrong but was the same race Senna qualified in monaco by over a second the same one he crashed out of despite not even racing anyone?
And tell me when Senna overtook 5 cars on one lap on wet donington in 1993, why was Senna starting that far back in the first place.
People should stop assuming Senna got pole by over a second in every race he competed in, or that he was the ultimate gentleman driver, he was dirty as schumacher is, and he was beaten to first place numerous times by prost.
Now i dont hate Senna, i just dont rate him above Prost, every other driver ever yes, but not prost. All too often the best drivers ever are the most aggressive ones that get fans on their speed (senna,hamilton,alonso,schumacher,vettel,mansell and so on) but Prost came in and had the cheek to win races through pure genius thinking and smooth style. Something nobody has since emulated, Jenson is on the same track but nowhere close. And in the season of 88 when Senna won the title over Prost, Prost actually had more points, the stupid system only counted the best results.
I respect that you saw these two racing for yourself, but the evidence isnt destroyed, i have found enough of it to form a decent enough opinion on the matter, if Senna hadnt been killed......well hed have have as less status as he does.
Here's the problem though with not having watched at the time. Senna already was looked on as a legend well before he died. Probably from around 1991 / 1992 even the British media and experts started to warm to him. By the start of 1994 it was a foregone conclusion in 99% of people's eyes that Senna would walk the title.
Ridiculous to cite the crash in Monaco, when he won something like 5 consecutive Monaco races after that.
I never said I disagreed that Prost was very quick - I said he was consistently faster than 95% of the field, and that was including racing against very fast drivers and cars in opposition.
Where did I say Senna was a gentleman driver? I know you didn't specifically say it to me, but in your post that is what is inferred. I know full well Senna was super-aggressive at times, and for likely around 5 years pretty much hated by the British media in particular, but that's not what made him quick. Senna was quick in all conditions, that's the thing - he was fast in dry, wet, tight slow tracks, fast sweeping tracks, even through traffic.
Again, aside from the fact they were team-mates, their driving styles are simply not comparable. They're both multiple world champions, so obviously both two of the best ever, but their driving styles being
totally different means that it
does depend on what you are looking for in a racer as I originally said.
Of course it's true to say that Prost scored more points than Senna - but all drivers on the grid started the season knowing full well how the championship was decided. Who's to say that is the system was based purely on points that Senna might not have eased off a bit in a couple of races and his car may have lasted the distance to pick up more points? Who's to say he didn't just go for it hell for leather because he knew that only Wins and podiums would cut it? Nobody that's who, we don't know and we never will. All we know is that under the conditions at the time, Senna was champion that season. Nothing can change that.
Why was Senna not on Pole in Donnington? Because he was in a well underpowered Ford Engined McLaren that had worse engines than both the Williams and Benettons. What clouds people's judgement in that race isn't that fact though, many people don't take account of the fact that Senna's car had Traction Control and Active Suspension, as did the Williams, though many other cars on the grid didn't - so he had more of an advantage than just his driving there.
Prost is an amazing driver too. I can't believe how competitive he remains into his mid-50's. As I say, I love watching him race, he is likely the most intelligent racer ever to have lived. How he stays consistently at the top amazes me, it really does. I genuinely think (and I'm honestly not joking), he could step back into a F1 car right now, and with the same testing as everyone else still be competitive at the top. I'm not joking, and people can laugh at me all they want, I genuinely believe that. Physically he is still in amazing shape and his reactions are sharp as they ever have been. It'll never happen, and sadly I doubt we'll ever see a F1 driver again racing into their 50's (or perhaps even their 40's once Schumacher finally retires), which I think is a shame.
Prost and Senna, both legends, but in my mind totally different and uncomparable as racers. Just my opinion, but I just can't see it.
