Fanservice is like chocolate.
Sure you might like it, perhaps even a lot, and sometimes it’s just the thing you’re looking for. But you can’t live off of chocolate alone, and any attempts to do so will only end in agony. Similarly, fanservice can be a welcome addition to anime, but if all the anime consists of is tits and ass, then it’s not going to be a complete, well-rounded experience.
Which isn’t to say you should never watch fanservice shows; it’s just that the satisfaction you get from marathoning To-LOVE-Ru is as fleeting as the one you get from gorging on a box of Russel-Stover.
If you want fanservice and a well-rounded show, go with Godannar.
