Entourage is marginally better than Outlook. It's generally less broken, and generally has a better UI, but try to, for example, send an HTML link. Hah! Can't do it, can you? It's not as if it doesn't send HTML mail, though. You still get that bloat (though, IIRC, it's reasonably easy to turn off) but not such advanced HTML features as "a href" links.
