God In Animeverse

I am planning to start the next phase of my novel, that is MC along with his girlfriends will go to different worlds. I had earlier decided to go with The Seven Deadly Sins but some people are saying Highschool DxD.

Perks of The Seven Deadly Sins----

1- If I do this it will be more fight oriented, so fewer girls in the Harem.

2- The power level is moderate, so after this world, he can go to One Piece world, Naruto world and so on.

Perks of Highschool DxD------

1- He will be in the same class as Hyodou Issei, get many girls(Big Harem).

2- With lots of girls comes a major update in the Realm of Violet Jade Immortal which will boost his strength.

As the name of my fanfic suggested, I wanted the MC to go and experience many different worlds but if MC goes to Highschool DxD, he will be there until he gets stronger than Ophis or Great Red, then move towards Divine realm.

In my personal opinion, I want him to go to many other worlds, which will be fun and not just stay in Highschool DxD even if it means not getting Rias, Akeno, and others on his Harem. (Because after going through, all other worlds he will be at least 25+. Not that it will affect him as after Ki training his lifespan will increase)

So, I want your opinion about this. If possible I want to know it quick as I have to read and watch the manga and animes of these series again to be clear about many details.
