I found To-Love-Ru much better than Kanokon.
Rito is a much more likeable male lead. He showed that he can act GAR when the situation calls for it. I can see why Lala fell in love with him, while Kanokon's "he smells like the countryside" is the most pathetic excuse for a love interest ever.
To-Love-Ru made me chuckle a couple of times, while Kanokon felt kinda dragged.
I also strongly dislike Kouta's character design and, while I love Mamiko Noto's voice, I found it unsuitable for a male lead. Sorry, but pseudo-ecchi scenes are not enough to keep my interest.
