I only have experience with Campy and Suntour Power Shifters, once their properly adjusted, I'd say they're about the same.
But, I'd love to try some of the various ones I see in this thread.
Here's a few pictures of NOS Suntour Power Shifters I picked up on ebay.
Seller had 10 sets (NOS) for $10 each.
In hindsight, I should have bought all 10.
