My version:
If you want to be generally better at Big cubes/Megaminx, do CFOP
If you want to be generally better at OH solving, do Roux
If you want to be generally better at OH solving but are politically opposed to table abuse, use CFOP
If you only care about being fast at 3x3, choose...

I'd like to know what the numbers are for "Quad Cross" aka Dual on two sets of colours (Half turn only because who cares about Quarter turn)
I suspect that the numbers would be basically the same as CN
I'm also interested because I know Max Park was Quad...

To be honest, I think sticking with one variant of ZZ is a horrible idea
Minimizing alg count might make sense in the short term, but long term the goal is to be competent with doing everything (this obviously requires learning the most amount of algs)
EDIT:
TTLL twisted cases have a lot of...

For those uninitiated, ZZCT was a somewhat recently developed variant to ZZ where once you hit last slot, you perform an algorithm that inserts the F2L edge while orienting the remaining corner pieces
From there you do an algorithm from the subset known as TTLL where you insert the final corner...

#1: Make it do everything this does - http://bestsiteever.ru/zbll/
#2: What Pyjam said. Make the scramble such that they don't give away info about the case you're getting

Another idea that I think could be worth exploring for improving Roux's inspection would be FB+DR+misorient SB corners & place in U layer, since having the D sticker of the corners facing up seems to lead to most of the worst cases. This would lead to a more "efficiency focused" SB finish...
