I had a 2007 1540 Powershuttle with a loader and now have a 2013 1643 Hydro with a loader. For loader work, the Hydro is hard to beat, but for virtually every other task, the Powershuttle is superior.
As far as comparing the two tractors themselves (aside from the difference in transmissions), there are some things that are better on the 1643 (headlights, seat, ROPs that doesn't vibrate near your ear, and one-piece hood) and some things that were better on the 1540 (a quieter tractor overall, better on fuel (both might be as a result of the transmissions, however), and the loader joystick was better than the new one on the 1600 series).
Again, since we use the 1643 more for the loader than as a "puller," the Hydro works well, but I really do miss that Powershuttle.
I also think that my old 1540 would out-pull this new 1643 Hydro.
I agree work you on the power aspect... I had an LS R4041 (41hp) shuttle, and it put much more power to the ground than my R4047 (47hp) HST.
I preferred the shuttle for "constant velocity" jobs like plowing and traveling on the road at speed, but for everything else, I prefer the HST. Even little things like hooking up 3pt implements, are much easier with HST
