Aptitude or Apt-Get
Was asked this recently, as far as I know the only core difference is Aptitude has a better way of handling dependencies when you remove a package; cleans up better. In all you should try to switch to Aptitude where possible, if you've installed a package with Aptitude then when you remove it via Aptitude it'll know about any dependencies it has to check for or orphaned packages.
