Yeah I got a Zen Micro a while back and like it as well.
The Creatives have superior sound quality, but unless you're playing super high quality files or are a freak about that stuff you won't notice a difference.
Battery life and features are other things to consider, though the newest iPods are very good with battery life.
Mind you I got my 5GB Zen Micro for $80, so that might make me biased!
