Only ones in recent memory (so...I'd say post-Ben 10) that I remember really enjoying were Ben 10, Chowder, and Adventure Time, and the former 2 aren't around anymore. Not really sure which ones you're referring to that are so good, but there was that one show...Bionic something, that wasn't bad. Other than that, I really can't think of any shows that I'd consider good and currently running.
Though I heard the Dragons movie was good, not sure about the show, though.
