The thing to keep in mind about 86 is that it’s a very grimdark kind of show (themes of racism, lots of character death). It’s a good show and worth trying, but if grimdark isn’t your thing, don’t be surprised if you bounce.

Hmm . . . so what else has no one recommended yet that’s worth trying. Gargantia on the Verdurous Planet, of course. You might find the earlier installments in the Aquarion franchise (Genesis of Aquarion, Aquarion EVOL, and Aquarion Logos) somewhat amusing—they’re more on the silly side, but so are some of the shows you listed (the first series especially has some very silly-weird stuff, like the episode where the characters are cosplaying each other).

Older shows that you haven’t mentioned and might be worth looking at would include Patlabor and Escaflowne.

And as someone has already said, do finish Gurren Lagann—it’s worth it.
