Poll Match 5
Well Koharu Biyori is an Comedy/Ecchi version of Chobits. 
(Also known as a Parody of Chobits)
That's why I picked up these two to make a Poll out of it. :P

Well, if I really have to choose which one I want to win it will be....
I'll say it after the Poll. XD

That's also a reason why 'Yui' don't really have a good background story. 
But I still think it's good enough information to judge it. :P
