You can choose. Their functionality is comparable, but with graid:
 - you can boot from any RAID level when RAID BIOS is present; you can
more or less boot from gmirror, but not from gstripe, graid3 or graid5;
 - RAID BIOS will know about failed, rebuilding, etc drives and will be
able to boot properly;
 - you can share/access RAID volumes with other OSes.
