If you are considering only the healers which can be captured through the quests: Saint Maria has the most healing power; Bishop Merith and Great Sage Mimir have a little better HP and Def; and Finkell has the ability to remove status ailments but has the lowest HP and Def of the group. My type preference would be Anima > Guardian > Lord > Breaker > Oracle. HP and Def are the most important stats because you need them to survive (also guard them when not using their BB).

If you are considering higher rarity units, Altri is my favorite because he can remove and negate status ailments for 3 turns and he has high HP.
