As someone who's current on Fairy Tail, I can say it's pretty decent, at least when it comes to the manga. I haven't watched the show in some time, and isn't the show on break right now or something?
Either way, it's got the "I fight for my friends" cliche dripping from everywhere, but that gets offset by all the fanservice, so neither get too obnoxious if you can stomach it at all. I'd recommend this FT to anyone who likes One Piece though, since they're pretty similar in design and execution. However, I would strongly recommend reading the manga over the show simply because it would take less time to read. When you read a part you really enjoyed, then I'd say go watch those moments/arcs wherever, and then go back to the manga, cause Fairy Tail is at maybe 200 episodes? 100? There's a lot...And while I have your attention, I'd say do the same to One Piece, cause it's just better.
A thing I really like about Fairy Tail, is that there are almost no cliffhangers in the manga or show. You never find yourself wondering, "Is that characters attack going to connect? Is the bad guy actually done? Whats this secret technique this character is talking about?" because 99% of the time, ny the end of a chapter or episode, it's been explained or shown to you.
