I went ahead and watched that top 50 video from above. I don't really care about the order. I just enjoyed seeing a bunch of ops and knowing that my choices for best are totally valid.
My favorite op this year in terms of both animation and song:
Death Parade - The way that it in no way matches the mood of the anime is strangely alluring.
Runner ups:
Yamada-kun and the Seven Witches
Charlotte
Kekkai Sensen (the ending is pretty top notch too)
Favorite ops based on song, in no particular order:
Nanatsu no Taizai OP 2 (okay, this one is in particular order)
Arslan OP 2
Mobile Suit Gundam: Iron Blooded Orphans
Overlord (I was also partial to the ending for this one)
