As u10ajf said earlier, people's style is usually a combination of their strengths and weaknesses.
I sometimes have trouble separating the melody from the chord progression when I hear a piece of music, so when I play it, I tend to try to do both at once. I've been a 'bedroom player' for more time than I've been in bands, so this trait actually fills in some of the holes that are left if I only play one part of a song. And I've never been particularly fast.
The result is that when I'm jamming, I kinda dance from part to part, adding bits here and there around what the others are doing. It's not difficult in a technical sense, but it seems to be unique. My ego is as healthy as anyone's, but I don't feel a need to dominate, so what I do works to enhance the overall sound, and it generally goes over well.
(And I do get a kick out of watching some 100-notes-per-second-super-dude getting tangled up in trying to duplicate some relatively slow stuff that just seems to come naturally to me!) :D
