Which ever one fits you best and you shoot the best. Also the one that you are going to practice with. What works well for me might not work well for you.
Here is mine. It's a Kimber Tactical Ultra II, feels great in my hand, I like the caliber (.45) and has all the carry features I wanted.
Good luck on your search.
(by the way the Bersa you metioned is a good gun.)
I'll second the kimber tactical. worth every penny
