Re: Best turrets-NF, USO, S&B
Assuming a quality scope, like one from either of those three makers, the 'feel' of the turrets is subjective and will also vary from scope to scope.
I like the positive feel of SB's single turn knobs, but others say the adjustments are too close together for their liking. I like NF, too, but how precise a NF adjustment feels to me often depends on how much grease is inside the clutch assembly. The USO EREK is OK, too, but I am not a fan of their Mil windage knobs - too light and mushy in my opinion (but to be fair, others really like them).
I have examples from each of the above maker, and I like them all. But, bottom line: I would first look at other things when choosing a scope.
