I'm looking for a top quality gun that I can use for a lifetime and its come down to those 3 choices. I hunt the marshes where I live on the NC coast and my buddy claims the finish on the Benellis won't hold up and parts rust and that the new SX3's finish won't rust. I'd like to hear what some of you have to on that. Also, how much difference in recoil does the comfortech offer cause I've never owned a satin walnut gun and the SBE II satin walnut doesnt come with comfortech, but still shoots a 3.5in shell opposed to the satin walnut sx3 which can only shoot 3's. I guess what I'm asking is, is it worth passing up the satin walnut look for the synthetic with comfortech. Also, how would satin walnut hold up to salty environments? Any help would be greatly appreciated.
