I'm not a fan of his per se, but Abi is one of the young rikishi I'm following. He's likable, at least to me, and I think there's still potential to grow. While he can be overeager and has some balance issues, he also has a lot of energy and speed, and I usually enjoy watching his frantic bouts.
As for the henka he used against Kotoshōgiku, I don't mind it one bit, even though I usually can't stand henka'ing. However, this isn't the first time Kotoshōgiku lost an important match in this way (Haru 2017, vs. Terunofuji comes to mind) and yet he seemingly refuses to address this weakness and keeps rushing in blindly. So it was a perfectly fine way to win in my book.
Having said that, at first I was quite disappointed with the way this basho evolved, but that changed in the last few days, which were very entertaining. The yusho race was open until the last day and decided in an absolutely satisfying showdown between Hakuhō and Kakuryū. As for many, THE match of the basho for me was Endō vs. Hokutofuji. I don't even like Endō that much, but his balance and footwork are out of this world.
