Archos is quite bulky and largely plastic dropped that a few times and got cracks and such. But there basically is no copy protection scheme (at least on the early ones), battery life is a bit lacking (but comparable to ipod but the ipod is rechargable etc).
Zen I don't actually own but I upgraded one for a friend and played with it quite a bit. Uses a normal laptop hard drive, better built the LCD is quite small. Good casing, well built but still is quite bulky. Can't really comment on battery life.
iPod is just awsome, I like the 10gb version as it is a bit slimmer, very well built, battery lasts a long time and it is rechargable. Only gripe is that the top plastic piece is not beveled around the edges feels like it should be. Also it gets quite warm when you are doing mass copys from PC. FYI copy protection scheme is kind of a joke, their idea of copy protection is that the files are in a hidden directory.
