When you say Takano Ichigo, do you mean the
manga-ka?
You can't compare a single manga to a manga-ka.
In terms of manga-ka, I really like both Io Sakisaka and Takano Ichigo, although I've read one series from each (Strobe Edge and Orange) both have really solid art and really top notch stories. I can't actually pick one that i like over the other.
I am watching Ao Haru Ride (also by Io Sakisaka) but have yet to read it. So far it's been very sweet.
