I have to disagree as well as agree here.
XXXHolic and Tsubasa are really 2 parts of one 
big new story from Clamp.
They cross over with each other lots and I 
absolutely
"Love" the princess Tomoyo bit.
Ho Ho Ho.....
They compliment each iother greatly.
XXXHilic is high drama and suspenese, with 
horror aspects, while Tsubasa provides a good 
traditional comedy/adventure/love story for all 
ages.
Sakura is cute too!!!!
So is Tomoyo...
Ack, the 2 halfs of my brain are arguing 
again.......
