I don't like to compare Eos' Embrace to Regen. Because of the way Eos is usually controlled (via Macro) it's more like a permanent supplement to your heals. She also targets whoever you target, or any ally below 60% health, so it's not just ticking away on one target like it does for Regen. With that in mind I consider Scholar's to be the better single target healers, but White Mages to be the better AoE healer. Sch/Sch is bad not because of regen stacking (Whispering Dawn can be stacked), but because galvanize does NOT. If two Scholars use Succor at the same time, the stronger shield will go through, while the other scholar only threw out a 150 potency heal.
