XFS is a very reliable, journalled filesystem designed for high performance by SGI.
Ext3 is not the same thing as Ext2. As Oddball noted, Ext2 is most appropriate for /boot.
Ext3 is now the "standard" filesystem for Linux. It consists of the previous standard filesystem, Ext2, with journalling added to improve both reliability and performance.
Well, ext3 may be the default fs du jour, but e.g on suse linux enterprise, the default is still reiser - and in my testing, when we were trying to decide on a standard filesystem choice for our new server builds, reiserfs beat jfs, xfs, and ext3 handily.
I've never lost a file in a crash or power interruption on eitherr XFS or ext3 -- and this includes a year in Baghdad when my laptop's battery ran out while work crews would take down a generator for 4 hours to do periodic maintenance and repairs. In contrast, reiserfs has not fared so well -- On more than one occasion, a crash or power outage resulted in lost files... and this was on my home machine which had far fewer problems... one power disruption and a few system hangs (running out of swap). It was due to this experience that I set up the laptop to use XFS. After a year and a half, and MANY loss of power incidents, and a couple crashes, I've yet to lose a file on this laptop.
In future, ext4, btfs and ocfs2 are all contenders for the "default fs" title. Unfortunately, Hans Reiser is embroiled in some legal difficulties which have clouded the outlook for reiser4.
