What reasons to play SGE over WHM or SCH?

[Vulkiel]

(This isn't a complaint thread, I just want to know more about SGE)

Been thinking of maining SGE as my healer, seeing as I started the game with Scholar and kinda miss the healing role, even if i've gone off scholar in general.

Ive been looking at it compared to other healers (Apart from AST, which Ive never had any interest in), and it seems a little bit lacking.

Being able to heal while damaging is nice, but I dont know if those damage numbers are that great anyway. WHM seems to do a fair bit more damage along with having more reliable heals and reacting to bad situations far better. When it comes to shields, SCH seems to just be overall better at that, too.

I've heard a lot of differing opinions on SGE, so i thought I'd ask here. Why do you play it over the others? What does it bring to the table that the others dont? (or dont do as well)
