D&D5e - What is the ultimate support?

This is an old topic, but I'm curious what a more recent assessment for the ultimate support build would be in D&D5e.

Previously, Treantmonk has pushed the idea of the 'God Wizard' who is built around spells that shut down enemies and empowers allies. Area control, vision control, area denial, and the odd buff to assist allies.

However since his build was popularlized, there have been a number of fascinating subclasses that are built around support, specifically between bards and druids. With that in mind, what are the best support builds? These are builds that help win the fight without dealing any damage, preferably
