I have the JBA and love it.
I haven't been researching exhausts in a while (since I got mine), but when I was the single out systems and the JBA in particular seem to produce the most overall gains (i.e. little/no loss of low end torque and torque/HP gains in the mid-upper rpms).
If you are getting a supercharger/turbo/ alot of internal engine mods down the road, then I'd get the freeest flowing exhaust like a Banks or Dual setup with a large y-pipe & headers.
If you are just going to do intake, exhaust, TB spacer, ECU flash/2* advance, and maybe the new JWT cams or UDP's... then the JBA will probably be the "best preforming" exhaust for you.
If you don't so much car about getting the most preformance and like the dual look and/or the Gibson sound, then go for the Gibson.
The JBA utilizes a straight-through K&N muffler and some don't like the sound of it at WOT. It has a sort of tapping sound when you get in the upper rpms at WOT, but that aside I like it's sound. I've heard that you can reverse the muffler to either maximaze torque or upper rpm hp and I'm not sure how that will effect the sound as I haven't tried it. It does have some drone at part throttle in the 1750ish rpm range like the other exhaust out there, but I don't find it intrusive.
