If you're set on one of them, I'd go Quake (provided your solid with her play style), or just wait for someone else. AA's damage at r4 is sufficient for almost any content you'd use him in.
I personally feel that your condiates are perfectly fine to deal with content at r4 I’d say wait a bit more if you get some champ like blade or ghost
As mentioned earlier ArchAngel is fine at R4 and not worth an R5, I would go gwenpool who is great for all or nothing paths in Act 6 and LoL or Quake if you're good
I would go Quake, Sym Sup is also insane for 6.2
I would go Quake, Sym Sup is also insane for 6.2 Quake and Gwenpool are 2 of my best O champs, love them both especially Gwen...SS is great but I'm not sold totally on him either.I guess it's all about the science and breakdown of what my needs are...I've completed Act5, need to 100%.I'm focusing on that, becoming Cav and the Variants.

Oh okay, Quake will help you lots then, focus on getting a Medusa, as a lot of bosses in Act 5 and 6 are melted with her as well as Caustic Temper Paths (need a champ with fury and poison immune). Sym Sup is more for 6.2 which sounds a very long while a way, wouldn't R4 now if you have better quest clearing options like Gwenpool, AA etc.Good Luck!
She was my 1st r5 and maybe im a little biased, its hard to dismiss quake tho if you are good with her. But man Gp got me thru my first LOL run and she still kicks ass for me in AW and act 6
