Yes, Schumacher always liked a stiff nervous car that everyone else found horrific to drive, which is a big contributor to why the gap to his teammates was so big at times. I'm not saying his teammates would have been faster than him if they liked the car the same way, but it's perfectly acceptable to assume the gap would not be as big if the other driver was as comfortable as he was.
I think you may have things a bit confused there though. Stay with me Im not being rude.
One way to make a car faster is to stiffen it up and make things, on the whole, more nervous. There is a balance between the theoretical speed the car can get and its drivability. You can make it easier and more comfortable but it costs you. The benetton was not that fast but it did lend itself to stiffening up and making it so the driver had to work hard ata it. MS didn't WANT a twitchy piece of crap, but he was able to deal with one, and therefore gain the speed benefit his lesser teammates could not.
Other really great drivers would no doubt have been able to use some of that speed too, but drivers who, in a nice friendly car, would have been a tenth or two off that great driver were suddenly all at sea.
