Both MariaDB and Percona are forks of MySQL. I recommended MariaDB because
that's what RHEL and CentOS are moving to for the default version of
MySQL.

Any of the 3 branches can be a good choice depending on your requirements.
In this case I took into account the stated distro as a requirement :).
Also, it might be t hat his version of CentOS doesn't have a 5.5 release
of MySQL, but does have a 5.5 release of MariaDB.

Percona is doing quite well, as far as I know. The Percona Live conference
was last week. Percona's backup tool is what I would recommend for InnoDB
in any version if you aren't using snapshots. I've even submitted SCaLE
talks on it :).

In the last three years I've used all 3 branches in significant production
environments.

ciao,
