With a tuned config I am very satisifed. With the stock config, not so much.

There are a lot of factors to consider. Generally speaking it depends on how much
(or little) administration you want to deal with. Also, they like to throw in the
occasional regression on those community releases - but that generally isn't an
issue.

Remember that in a worst case scenario you can always dump your DBs in and out of
the two version to upgrade/downgrade (note the compatibility option with mysqldump).
With some data sets this might not be practical, but there are various things you
can do.
Anyone is free to contact me off list if you have any CentOS+MySQL questions. I
currently admin several thousand MySQL servers. I'm not going to drag that out in
this list as the point is CentOS, not really MySQL. On that topic I am very
satisifed. MySQL runs great on CentOS 4.4.
