We use a Reese with a 27' FB. There are "religious wars" about the brand of weight distributing/sway control hitches on this forum every once and awhile.
I suspect that the "truth" in performance has more to do with a properly set up hitch for the specific TT and TV in use than the brand. In your case, you should see if your existing hitch (the brand of which you did not specify) can be adapted to work with your new larger TT. In the case of the Reese (which I am of course familiar with,) switching to a larger trailer would require getting beefier torsion bars and adjusting the ball height and angle, a fairly simple thing to do. I would suggest that if you are not comfortable dealing with this on your own you seek out a reputable dealer for your brand of hitch in your area and go see them.
