To cut a long story short:

- ext3 has a single bonus, and a huge one: it is basically ext2 plus a
  journaling layer. ext2 tools may be used on it, if necessary;
  moreover, the core structure has been in use and extensively debugged
  for years
- reiserfs is a clean design, boosting impressive performance even with
  lots of inodes. It also allows for less storage waste, which may be of
  interest when coping with zillions of small files. Even if you didn't
  mention it, SGI's XFS is in the same arena, and should be taken in
  account as well if you work with 2.4.x kernels; IBM's JFS is rock solid
  in itself, but IMHO is not a suitable choice in most cases since the
  Linux implementation so far lacks full support for VFS extended
