Best Support?

In the current overwatch meta, what is the best support?

I know i can just look up a tier list, but i would like to hear your guyses opinions and see what do you think about it, or at least how it is going in whatever rank you are in! What is the best support for the chance of winning?

Moria.The healthper second say it all.

Zen and Ana are in a good position right now.

Zen can do a lot of damage, his discord orb is good in general and his ult is almost mandatory in some cases.
Ana's kit is good overall, her sleep dart and anti-nade can decide if you win a teamfight.
