I would say Zoro vs Lucci stands out as even more shit. Negative choreography constant cuts to meaningless clashes, and just like 4 pages of fighting.
Sommers is at least entertaining, Lucci didn't really play off Zoro at all
The Lucci fight sucked, but it gave you no reason to think less of Lucci. He was competitive and still standing when it ended.
Sommers is an entertaining villain because he's so expressive, and I didn't need him to be super powerful, but as far as the fight goes, I don't know what's less engaging than his constant terror and ineptitude. Dude was established as a punching bag before it even began. The only good moment had was blocking Dragon Damnation, and it was straight back to this goofy shit.
The Lucci fight at least had the tension of him tying up Zoro, preventing him escaping earlier or going to help his crew. There was a race against time element that could be felt.
The Sommers fight has 0 tension. It's just a tick box for Zoro learning aCoC, and no one really anticipates Zoro to do anything interest afterwards. Maybe it'd be different if it happened in a context where Zoro is trying to get to Luffy, but Sommers is standing in the way.
