I think its really personal preference and what you get used to. Most target shooters I know prefer a 2 stage. I prefer a single stage with little or no creep and over travel especially on hunting guns. But I've always coached shooters to shoot a 2 stage, mostly because that is the way our clubs guns are set up.
I really like a 2 stage for a precision rifle. It creates a nice dual purpose gun. I have a cmc 2 stage that is 4# total, but it’s 2#/2# on each stage. Makes a great light trigger for precision shooting, but a nice safe 4# trigger for other things like 3 gun.
I get a chuckle when I hear someone talk about a 4lb trigger being light (I know it is for an AR, most handguns and hunting rifles). I coach precision air rifle and smallbore. The guns are set up with a 100 gram trigger, which is about 3 1/2 ounces.
