Super Robot Anime suggestions? - Divisions by zero

I’ve seen Gurren Lagann (10/10), Code Geass (8/10), and pretty much all of Neon Genesis Evangelion + movies and rebuilds. Are there any other really good super robot anime? I watched Darling in the FranXX and had a good time til about episode 18 or so when it jumped the shark. At one point I tried and dropped Eureka 7, just seemed really childish? Might need a revisit, but the MCs being so young was strange to me. What other mecha shows are worth the watch? I haven’t ever seen a Gundam show, but did watch Zoids as a kid, hah.
