Nope... I'm still giving that to Cardcaptors.
As for something I would like a second season too, eh, most of the stuff I enjoyed enough ended well enough. I'd rather a series be over than see have a garbage second season.
I think the only thing I'm REALLY salty about not getting a sequel was the 'Guardians of Ga'hoole' movie. Not an an anime I know but still... if there was one move I wanna see continue through the franchise it was that one.
