company-mode's popup is also far from rock-solid (I have no experience
with auto-complete's popup, so can't compare). But FWIW, I'd like to
move company-mode into the core completion code.
I've implemented a bridge between company-mode and
completion-at-point-functions ("company-capf"), and moved company-mode's
completion tables for Elisp into lisp-mode.el. But there needs
to be some further integration work to make sure company-mode works well
with existing completion-at-point-functions.
But it wouldn't be enabled by default, anyway.

Oh, that should be reasonably easy. Just add the corresponding
key-bindings in minibuffer-local-completion-map, mostly. The main issue
is to try and avoid clashing with existing bindings (since there are
2 buffers at play: the minibuffer and the *Completions* buffer), and
without C-x o, you're still in the minibuffer where left/right should
still mean "cursor movement in the minibuffer".
