I'm running the ACT on two of my rifles and I find the triggers to be great. They're like Glock, boringly reliable, everything you need, nothing you don't, and is a huge improvement over a hi-point(milspec trigger). I find them very smooth and crisp on the break, and you can still run the living hell out of them.
In my honest opinion, if a standard curved trigger shoe is what you want, get the ACT.
If you want something more Gucci like a flat faced trigger, go with a geissele.
The only types of triggers I stay away from are any of the "closed trigger pack" design like the CMC or trigger tech, only because they're by design (and proof) to be somewhat less than reliable than the typical open design.
If anyone is on the fence about upgrading a basic milspec to one of these, trust me on this and just do it.
The ALG ACT is a phenomenal trigger, especially for the price.
