Personally I'm a fan of both, although I'm more versed in real robo having watched a lot of gundam and some macross movies. I'd say on the fun scale, super robot is all about that goofiness that defines anime while real robo has some good stories to tell and mechanical designs that wow you.
I love obsolete, i mentioned it in the second of my massive unformatted text blobs lol, its politics are decent iirc, mentions how imperialism causes wars/child soldiers, mentions that the USA is slow to adapt to the arrival of the exoframes due to entrenched business interests, even has an episode where the protagonists are immigrants crossing the US border illegally. not necessarily based commie propaganda, but nevertheless free of several of the more virulent strains of brainworms.
