I like my Suntour XC Pro and Shimano DX thumbshifters, but I've had thumbshifters I've hated.
I like my Sram SRT-600 and Attack Gripshifters but I just got a bike with SRT-100 Gripshifters that are crap. (I should add that my SRT-600s are coming up on their 20th birthday and have LOTS of hours on them. Worrying about replacing them hadn't resulted in any lost sleep)
I couldn't stand the push-push style under-bar shifters from the early 90s.
Not enough hours on triggers to really have much of an opinion on them.
