Honestly, it's pretty silly to compare both, since both of them together are better than sticking with only one type in your whole party. That said, if you did want to compare, you could do a much more in-depth analysis on survivability.
For healing? Nope, Cure Wounds is a good single nuke heal, but it has a lengthy cooldown. Water heals beat the pants off it.
Cure Wounds is a trash skill after level 10 to 15, why? Because you don't even need it as a warrior for survivability, by that time you could easily achieve 100%+ in the four magic resistances. You'll heal up so much from enemy elemental attacks, physical and tenebrium attacks become almost meaningless with the resistance healing and also leech, which is more effective for front line units since they can tank easily with 6+ enemies surrounding them.
