I may be alone in thinking this, but i just couldn't get into the manga at all. I loved the anime because while it felt balanced..had its serious moments, it's ecchi moments, absolutely hilarious moments..nothing felt too overdone.
A friend of mine kept up with the manga and every little bit I heard about it just killed my interest more and more..people dying left and right, everything getting serious and over the top..mechs and oracles and all kind of crazy nonsense..for me it just felt like it had a nice balance then they decided to take everything WAY out of left field and just run with it.
Maybe he was just highlighting the more serious or crazier moments but..eh I just liked it how it began.
Except the anime wasn't balanced. They threw in random crap.
The manga was actually good and balanced. It gives a deeper look into the characters, if you don't read it then you won't have all of their character development :s
I think you should give it a chance, it gets a lot better towards the end and it's action packed.
