User blog comment:TrueHeavenlyDragonGod/Whom would you choose out of the girls around Issei?/@comment-23847729-20140201042752/@comment-24468758-20140203172922

Personally I like Rias the most, but I would choose Akeno.

Akeno and Rias are both dependable, great cooks, intelligent, beautiful, elegant and erotic (nearly forgotten).

You already listed some of Rias' other good aspects under point 1.

In comparison Akeno's personality is fragil and depending but as long as she has some one she can depend on she is also strong, furthermore Akeno has both sides S and M which can lead to quite interesting situations.

In the end Rias and Akeno are nearly even, since in my opinion one of the biggest diffenences is that Rias is more romantic and Akeno is more erotic (in the erotic situations nearly always Akeno takes the lead and is the main reason for increasing the erotic level by far as seen during the erotic cosplay when she increased the level and Rias tried to surpass her).

At last an example why I would choose Akeno: in volume 15 Let's Go with Training - Hell Chapter I instantly thought "I want to be in Barakiel's stead!" just because it seemed exiting. And I think Akeno could do things which are far more exiting than that.
