I am not a basher but I had a Gissele SSA-E on my rifle and didn't care for it. Longer take up and reset. It was on a 3 gun AR so I was thinking of trying one of their 3 gun triggers until I felt one as well. Didn't like it either. Felt like there was drag in the take up. Didn't feel smooth. Ended up selling the SSA-E and got a AR Gold. Like it a lot better. Another trigger I want to try is the Hiperfire. Played with one and it was really nice.
Don't be jumping on me because I didn't like Geissele triggers. Just weren't for me. If you like them then great and run with it. They have a great reputation.
SSA is like mid/low tier as far as Geissele triggers go. Run behind a Highpower or DMR and its heaven. Their Full auto trigger is also fantastic for duty weapons.
