Fairy Tail didn't win anything. I consider this a defensive victory. Hopefully this years people took notice of Vinland Saga and picked it up. Hope it it will have a strong 2017 to shine next year.
But the awards are mostly pretty deserved. The big winners (OP, OPM, HxH, Bnha) are totally worth the praise. Neverland keeps the good work up and works on it weak spots, and its also gonna be a strong contender next year.
