The six speed is about the same as the AX-15 as far as strength goes. It's gearing is a little more stout, I think it's overdrive is a .8 or .85 compared to .75 or so in the AX-15. It does have a nice and low first gear though.
From what I've heard, folks with the 4.0L wish they would've stuck with the NV3550 as it was a stronger tranny, but for the 3.8 V6 going into the 07's, it will probably work better.
IMO the NV3550 shifted better and seemed less noisy. But that's the comparison I did on a 02 TJ and a 05 LJ (unlimited Rubicon)
