Hmm, it's my default undo system and I wouldn't say I use it only rarely. I use the tree visualiser at least a couple of times a week.
Honestly, though, I believe any imaginable undo/redo system that keeps *all* past states of the buffer accessible would basically be a variation of undo-tree. And from a user POV, undo-tree is quite straightforward and easy-to-use, IMHO. It certainly has some bells and whistles that look impressive but may not be very useful in practice, but that doesn't change its basic usefulness.
Grafting a redo on Emacs' current undo system may be possible as well, I can't say, but I can't really imagine what such a system would look like. That may just be my lack of imagination, of course.
OTOH, some of us experienced catastrophic failures while using undo-treeconsisting on the disappearance of all undo information.
That's not good, obviously. I never experienced anything like that.
