just got done skiing the bent, rocker 2, jj, tst, and S7 for industry demo
the rocker 2 was the most fun, best pow ski.
Personally i am getting a jj first before a rocker 2 due to the versitility. the jj (and every review will tell you this) is just ultimate versitility. It slays everything!
the bent is a little bit wider, so better float, but not as easy edge to edge.
Assuming you mean bentchetlers and not hellbents i would go with the jjs.
I have bentchetlers and they have few advantages over the JJs. The JJs have more shape, hold edge better, and are stiffer while still floating. The bentchetlers are more playful and softer, also they float a bit better but its pretty un-noticeable.
I'd rather have JJs than my bentchetlers but i still love them!
