I've noticed that while the transform tool moves things smoothly, even with rotations and scales thrown in the mix, the simple move tool is slow and choppy with tearing like in GIMP. Did someone add GPU acceleration to one tool but not the other or something? It happens to me both in Windows and Linux.

Another thing, is there actually any benefit at all to using the move tool if it is both slower and does less?

It's more precise: the transform tool shows a small, scaled down preview on top of the layer stack, while the move tool moves the actual layer in the layer stack -- which means every move recalculates the entire projection.

Okay, I guess I didn't notice that it was a small preview due to the sizes I was working with. However, I noticed that the issue of a slow move tool is listed as a regression here: https://krita.org/en/item/krita-2019-sprint/.

I think that was referring to this regression: https://bugs.kde.org/show_bug.cgi?id=410838 which has been fixed for Krita 4.2.6.
The Move Tool is still slower like Boudewijn said, since it uses the full resolution and renders blending modes and layer styles during the move operation, which the Transform Tool doesn't.
