Druid tanking seems like it sucks big time, boomkin dps is godlike, healing seems ok?
Monk tanking seems cool, dps is melee / fine, healing seems bad?

I'll be doing pve and pvp, with a hunter

Any insight?

Tank - BM > Guardian
Dps - Feral > Others
Heal - Resto

So monks surpass on the tank side. (In my opinion)

Guardian is ok. Pretty much any spec right now is good if played correctly.

Yes, but he's asking for the best between the two classes.

I'd suggest monk, all three specs are great, monk healing is actually really good and people seem to think otherwise for some reason. Windwalker is obviously OP as fuck. and brewmaster is crazy, if played correctly you can literally outheal healers.

Agreed, but people avoid playing mistweaver because of the huge skill curve compared to Resto druids.

If the brewmaster is outhealing the healers, you need to find a new raid. (Or you're spamming Guard like some scrub rather saving it for critical moments)
