I prefer the gunsmith fit wilson high ride w/bump. I have my smith contour the tail a bit, and its perfect for me.
I also like the Brown, but for me its a tad too high, i like to have some of the tail pushing into the web of my hand, get better control that way.
Another reason i like the Wilson over the Brown, it that the Wilson fits up better in the Springfeild frame. Seems the Springfeild frame tangs are set a bit different and hard to fit the Brown, requiring a re weld etc....
Any how, both are excellent products, as well as the STI mentioned.
I think the most important thing is to have it fit by a good smith etc...
