So I don't watch shows as they air. I prefer to wait until they are finished and watch the season in a short period of time. That being said I just finished watching GJ-Bu. Oh man that show was just so cute and lighthearted and amusing. If you enjoyed K-On or other shows like it give GJ-Bu a watch, I think you'll really like it. If you aren't into that stuff I don't think GJ-Bu does anything different that will change your opinion.
Next up I think I'm going to watch Senran Kagura. Yeah that's right I like to watch dumb fanservice shows.
