Thanks for the comments everyone.
I like both of the click styles. Both work very well.
I do prefer the one from PSI for the click mech.(smooth, solid feeling click), but I prefer the looks of the sierra (the click mech. sounds a little cheap to me), but does work well.
The owner at WC told me the sierra was only offered in the gold, but when I went to AS, Bill has them in several platings.
