Man in Steel has a lot going for it and for me is head and shoulders above everything else they've done, by an absolutely insane margin as well.
MoS, while Zod/Superman were utterly stupid to not have a, I'll give you the codex freely, just go colonise a different planet, Zod was cast brilliantly and acted superbly, as was Superman and almost everyone in the film. It had a real tonal feel throughout that felt consistent, the sound track was pretty amazing, it looked great. It's comedy moments were there but didn't feel out of place or out of tone or the moment and worked.
In Aquaman the tone isn't consistent, one moment it's trying to be dark and sinister, the next it's trying to be a rom com(the arriving in the Italian village moments were all cringeworthy crap). It missed the target on all these attempted tones, it wasn't actually funny when they tried to make it funny, it wasn't actually serious/sinister when they tried to be because Momoa can't really act, dark, brooding and not speaking he does well... trying to give a speech where he's got this kind jokey tone/cadence to his speech doesn't work.
Aquaman was poorly cast, poorly acted, tone was all over the place, dialogue was garbage and never sucked me in at all.
Compared to Aquaman, Man of Steel is a straight masterpiece. Compared to Justice League, BvS and most of the rest it's probably around on par. Wonder Woman started off okay but almost everything after they leave the island is all over the place and not very good. I'd still put it a good way ahead of Aquaman.
