[jQuery] Choosing an Autocompletion solution

[jQuery] Choosing an Autocompletion solution


I searched google for "jquery autocompletion" and was overwhelmed by
the choices. Looks like people have been borrowing heavily back and
forth to get the best solution.
Has anyone gone through the choices recently and selected one? If so,
which did you choose and why?
I'd like to use it for both local and Ajax server data.
