Quite a selection! My bikes also vary a lot. At least mine all feel different - helps out a bit.

In order of preference (most fav to least fav):
Bar End shifters on the long distance bike
Brifters (STI) on the road bike
Trigger shifters on the hybrid
No shifters on the single speed
Grip shifters on the old mountain bike

They are all shimano, but I can't remember what level anything is.
