the only gundams i'd say are even remotely on the same level as unjust depths are turn a gundam (basically a perfect show, not openly communist but like, has a material understanding of the world that never goes away and hates the industrialists, protagonist is probably trans? reads as such to me) and iron blooded orphans (about struggling against imperialism, but mostly about dudes and some of the women aren't treated amazingly) and though turn a especially is hitting hard i still prefer unjust depths
