I was quite fond of Enemy Territory: Quake Wars, but I haven't played the Wolfenstein one.

Opposite for me. Never touched Quake Wars.

If you want to play the Steam version of Wolfenstein: ET, you'll probably have to modify the files with ETLegacy to get it to run on modern computers. It was pretty simple to change out, especially if you follow the guide that someone posted in the reviews.
