They are similar in quite a few things. Both includes Devils, that made a contract with some guy. The main girls also both have red hair and are hot. There are some dissimilarities though, cause DXD is jsut full of Ecchi and Boobs. Both are great anime

In some way, they just really seemed similar. Both are about a guy who uses a sword and has a contract with a girl. There are also magicians in both and they really have a similar style. In zero the harem is quite important though
