"Nobody told me about this!" - Jin realizing he's a villain in Kamen Rider who never get informed ahead of time when they're about to get beat up by the new upgrade form.

Shining Assault Hopper! Honestly I just think the funnels are really cool. Like, I'm a big Gundam guy so just seeing a Rider use funnels to fight is cool for me.

I feel like Aruto vs Jin works just as fine because technically Aruto's been dealing with Jin from the start so they've got that going for them and Jin's innocence and nascent obsession with fulfilling his fathers' wish makes for a nice contrast with Aruto's resolve to stop them even if on some level you wish these two could connect and do more than fight each other. Like Aruto is his family's legacy while Jin is the legacy of Metsuoboujinrai and their philosophy, so that's why I think the fight works. And Jin's last moments are pretty powerful to me.

And also just the overall direction and impact of the fight is great. Still showing off how awesome and powerful Zero-One is now but Jin still fights as hard as he can. And it ends really the most powerful way a duel between Riders can end...with them Rider Kicking each other.

The Metsuboujinrai arc has concluded and now it's time for Gai/Zaia to take the stage, and he's a much more smooth and open operator, especially since he was technically behind everything and using it for his own schemes. Really getting our new antagonist out there and establishing why he's going to cause more problems. And there's still the active Magia too...
