I haven't experienced a bug with ext3 yet (or ext2 for that matter).

ext3 is more resistant to system crashes than ext2.  You won't
necesarily lose less data, but you will avoid filesystem corruption.
This means that existing files will still be existing files as they
were, though new files/data my not be stored to disk yet.

ext2 and ext3 are just fine for me.

ext3 is just ext2 with a journal added (in a "hidden" .journal file).
If you have an older kernel without ext3 support you can still mount
the fs as ext2 and ignore without the journal at that point.  Then you
can mount it later as ext3 (with a kernel that supports it).

AFAIK the other systems are not in any way compatible/interchangeable
with others.
