Which will get me laid more?
Sorry man, neither in your case 
Unless of course you mean laid out on a stretcher, in which case the answer is ..... the bike. 
Yup, hence why I stay well clear of 'em 
When I was young (and maybe not so smart), I choose bikes over cars. I was deathly afraid of fire and having seen the horrifying conflagrations that punctuated auto racing in the 60's and 70's, I decided breaking a collarbone or losing a little skin racing motorcycles was infinitely better. As it turned out, I was not a success on 2 wheels. I was fast on occasion, but as my gf says, my enthusiasm far exceeded my skill level with predictable results. Still, I think I chose well .... after all I emerged from the experiment a little poorer, but relatively unscathed.
On topic .... I would choose the MotoGP machine. Despite my ineptness as a racer, I still had the opportunity to test ride (not race), both an 80's Honda superbike and a TZ350. Those experiences would help me at least keep a MotoGP bike on track, though you might need a calendar to time me. Besides, I am much more consistent at the PS2 Motorcycle games than GranTurismo.
Le coeur a ses raisons que la raison ne connaît point.
