For me, the only real difference between Bleach and Fairy Tail is that Mashima isn't getting his arse rushed to finish everything within a few chapters, my man has all the time in the world to fuck his shit up.

Thematically it's essentially all the same thing happening: the mangaka writes an antagonist into the story that is way too powerful for the protagonist cast to even handle, let alone defeat, so much so that only the mangaka can save them (typically in the most bullshit way possible). Although, when it's got to the point where only the mangaka can save the cast, you can't really expect much better.

Bleach had Yhwach, Naruto had Madara (and to a lesser extent Kaguya) and Fairy Tail had Zeref and Acnologia. All three dealt with with them terribly, to say one ending was worse than another would be mostly bias. The only way FT could somewhat redeem itself put itself above the other two aforementioned series is if Acnologia came back and tore everyone a new arsehole... but I doubt that'll happen.
