I went through the same dilemma with mine. Turns out, that I was asking the wrong question. What I should have wondered about. Is, do I want a single, or a two stage trigger.

So I spent quite a bit of money on a single stage hyperfire. It's a very smooth trigger, with an adjustable pull weight. I like it well enough, but decided to get a two stage Gieselle. That was the best decision for me. If I'd only known that I actually prefer the two stage, I could've saved a lot of money. Turns out that I really don't care for a super light trigger pull in a single stage.
