Kobato, as you know, is by CLAMP, so there are lots of similarities overall, as well as some characters. The artwork is amazing with the nice colors and the touch that makes certain characters lovely or not. The songs played in the background as well as songs that Kobato herself sings were all perfect for the anime.
The story itself had times where it dragged on imo, but in the last few episodes, they were wrapped up so perfectly, and the final episode is one that I'd consider the best ending I've ever seen.
I enjoyed watching Kobato for lulz as well as just experiencing the adorableness. It's an anime I'd highly recommend to pretty much anyone.
