When I used to run Ext2 with redhat 6 - if the server crashed often it
failed to com up on the next boot without someone manually going in and
running fsck with meaner switches. The entire process of rebooting after
a crash often took an hour - and it was a very tense hour - wondering if
it will come up even then.

Since I stated using reiser those probales went away. I also had some
drives (IBM Deathstar) that were slowly dying from sector failures and
in spite of these failures I was amazed with how well it maintained it's
integrity. So - in my experience - I think itr's far more solid that
ext2 and I don't think anyone has to worry that it's ability to recover
is less that ext2.
