Both anime's follow a similar style. Chobits is a little more innocent in terms of sexual scenes where as Roasio to Vampire's sexual scenes are literal. Both anime's can be geared towards both males and females, though I believe males might find these two slightly more enjoyable. There's a few cutesy moments in each of them but the majority is literally mindless sexual references backed up by a minimal plot line.My recommendation is that if you don't mind sexy anime's then give these two a shot.

Effective immediately, Shido must date Spirits and make them fall in love with him, because if he cannot, mankind's destruction may very well be inevitable.
A male lead surrounded by powerful supernatural creatures who so happen to have an attractive female figure. Actually the female figure is probably a main character in it's own right in both anime as it get's a lot of focus. Both series sport a token loli-type girl while the rest are considerably endowed. In both series the male lead is very much the underdog powerwise but Date a Live gives the male lead some survival tools while Rosario to Vampire's anime does not. The premise in both series revolves partially on not pissing of said powerful girls however that's where the similarities end, both have very different settings beyond what I described above but both rest firmly in the harem genre.
