The manga crams a lot of stuff into each chapter. For basically this entire arc, the anime has been 1 to 1 between their episodes and the manga's chapters. Sometimes it feels like it moves almost too fast, other times its just like the anime - you just can't wait to see what happens next.

Then there's the typical differences....less censorship, less low-budget cheese, etc. The music is usually the best thing the anime has to offer.
