Difference between original and bunny Mikoto?

I got both due to 4th anni and thanks gara, but i'm not sure which one to use.

Does anyone here know the main differences between them?

Have you read any topic about her in this box?

I read http://www.cosmicbreakfanforum.com/t14782-need-help-with-build-with-tsukuyomi-mikoto
but the only difference I've read is that original has better AM and can use AMJ. Is that all?

yes

oh, thanks.
