I don't know...Schumacher had this aura of 'fear' about him, as in other drivers actually looked up to the guy and feared him for his skill/ruthlessness. I remember my feelings when I first started watching the sport, when supporting the real McLaren of last time in late 90s, Mika VS Michael...whenever Michael comes out of the pits for qualifying, I'm all like "damn...". And the paddock shared this feeling.
With Vettel however, we have Alonso and Hamilton who has more respect for Adrian Newey than Vettel. It's like half the grid think of Vettel as this lucky rich kid who has gotten his success through superb timing/fortune...with Redbull and Newey. Unlike Schumacher who worked his way into Benetton, then left after 2 WDCs into a lousy team called Ferrari and worked its way up to dominance. It's a completely different philosophy. So even if Vettel wins 10 WDCs with Redbull, everyone on the grid are just going to be like 'meh'. No one can love to hate the guy unlike with Schumacher..Vettel's like a Bieber, innocent lucky kid who's riding his fortunes. Good for him anyway.
