I've been playing bass with a pick since 1976, but about a year ago, I started playing more bass again, and I felt it more natural to use my fingers, which I prefer now. Years of playing guitar with a combination of pick and fingers seem to have helped my bass fingers as well.
I don't think using fingers is better, just different, and some songs call for one, some the other. So I don't feel like a snob about it either way.
Do you use fingers and picks or just one or the other?
