My top tier is OP 10, 7, and 3 in that order. I enjoyed Vickeblanka's songs the most and OP 7 was all around a great opening. In addition to what Hermit said, in OP 7, I liked the scenes where the Golden Dawn turned dark on Mimosa and Yami screaming before Julius and Patri fought, music was on point. And in the original OP 10, the end scene with Secre and Lumiere/ Licht was well done.
Must say OP 1 keeps climbing for me, was basically a coin toss with OP 3. Probably bc it plays in big moments like Yami's dimensional slash equinox and Asta and Yuno vs. Licht. After that I got OP 5, 6, 8, and 11 in the same tier. Op 5 always gets me with the Vanessa focus, the tone/mood of OP 8 and 11, and OP 6 is pure hype of the royal knights arc. Last tier is OP 9, 4, and 2. It's not that they're weak, I feel the others are just that strong.
