New Thumb Safety: Opinions Needed

Since my Dan Wesson has the dreaded "horny safety," I have decided to replace it and (hopefully) save the webbing between my thumb and index finger. So far, I have narrowed my options to the following models from Wilson Combat. I am already leaning toward one over the other, but I also wanted to see what you guys think.

This is strictly a range gun, so holstering/concealing/etc are of no concern to me.
