Aptitude is supposed to be more "high level" or some such, but I've never actually seen a case demonstrating that.
It would surprise me if dpkg did not also need some form of update, to avoid fetching an old package version.
As far as I understand, apt-get and aptitude are basically an abstraction layer which interact with the repositories, relaying on dpkg (or something similar) to install/delete package files on the system. Anyway, there aren't any cons in installing a downloaded package through dpkg, once you are sure it is safe. Of course the isn't any automatic update of that package, but that's the only way to install a third-party packaged not included in any repository. -- Mick
