Knights of Sidonia has great visuals and lore ideas but boring storytelling and characters.

Argento Soma had interesting aliens and story but the robots were pretty basic looking.

Bokurano has great visuals and very interesting story, but it has some heavy topics. (Epstein related…) Also I think the manga is better, but the p is worth just for the song.

Fullmetal Panic has move robot battles, but you might not like the combination of highschool sillyness and serious war story.
