I say it depends on your style of play:
If you're more of a PvE person, and don't like to sp farm much, you can just go with Xbow / Bard...though note its strength isn't in solo pvp.
If you're more of a PvP person, Cleric seems to be the better choice. Recovery Division, Oblation, Group Res, Healing Cycle, Body / Soul Deities, and Scorn are helpful in group fights.
EDIT:
You can read up on Xemnas' Rogue Guide. He goes over subclasses and what they offer here:
