sure.
first of all ext3 is the default across all distributions
(suse switched since some years ago from reiserfs too ext3).
secondly the ext3 performance troubles were mostly fixed for 2.6
the remaining ones will be fixed in ext4.
third ext3 devs care much more about data integrity.
fourth reiserfs still relies on the big kernel lock
this gives it really bad latencies.
fifth we see traditionally lots of reiserfs corruption reports
(although only a fragment of our user base run it).

recent benchmarks show xfs and ext3 quite on pair with xfs
on the lead for ext3 design shortcomings.
modern design wise ext4 is catching up with xfs.

hope that helps
