I used to find iTunes OK, back when DAAP worked and I could just access music from my music server. Then Apple broke that, redesigned the interface several times, and crammed in yet more junk I'll never use like iPhone app management.
I got so sick of iTunes and of having three different mutually incompatible proprietary cables for our iPods that I got rid of all the iPods and replaced them with MP3 players that just mount as regular disk drives.
Now I use Vox for music playback on the Mac. Bonus: It handles FLAC, unlike sucky iTunes.
