Akikan and Sekirei are more comedy focused, whereas the other two are somewhat more serious (though there's a lot of silly things which go on in Rozen Maiden, so one may argue that is has a fair bit of comedy focus too).  So yeah, Mai-HiME would be more your style.

Also note that the guy behind Akikan and Sekirei is some dofus whacko, which I find entertaining.
