mastery is by far better
the bigger question is how haste goes up against crit and multistrike, and the fact that having a decent amount of haste for shorter gcds is very nice in general
haste does not affect tranq (20%~) and the small 5-10% of direct healing, but it buffs shroom, rejuv, and wg which are our main heals in regular healing intense situations, so it's likely better than those 2, although not by a large factor, so in regards to total healing done, it's about as good as versatility, but in reality should be ranked a bit ahead of crit/multi
and as I said above, keep a decent amount of haste or else it just isn't pleasant to play
