I think you will like your Browning, I love mine. The FTF reports were from very early 3.5" Golds, and the problem was resolved a long time ago.
I have had plenty of SX2's and Browning Golds apart. I have not noticed any difference on the "beefiness" of one over the other. The only jams I have known are from an extremely dirty gas piston, or the action tube in the stock. On mine, I clean the piston every so often, but never have cleaned the action tube. No problems at all.
I have dunked it in water, had ice covering 3/4 of it, dropped it in mud...you name it, it just keeps on ticking.
