Ooh, glad you asked! I have the subbed anime and all the manga, and there are some differences (mostly towards the end of the series). I see the anime as an in-depth view of the manga. You get the inside story of the other deuses. Like, why Kaede is so sweet, why Sai is so reserved and confident, why Madoka is deep down a truly cool person (she's my fav deus if you can't tell), and why Alice is such a turd. Also, the fun minor characters, like Ringo and Tamayo get more of a spotlight and only make the story more colorful. As you can imagine, with so many battles, the animators would use the same scene every time for Hikaru's Layer entry. The animation is great, and the characters are all true to the manga. I'm afraid if I tell you some of the major differences, that it'll ruin something in the story for you. But you'll see what I mean . . .
Here's kinda a fun (and really short) quiz. I got my fav Angel, actually.
Which Angel Are You?
