Uninstallers

What is the BEST standalone UNINSTALLER there is out there? Norton’s Cleansweep has been failing me for years. Can not monitor installations without crashing. Can not uninstall without crashing.
So what standalone uninstaller out there is the best?
It has to be able to do the same things, and more, that Cleansweep can do: monitor all changes during install (files and reg), uninstall everything that the installtion did, backup the uninstalls, reps, etc.
Thanks.
