Any chapter with Yuri is a good chapter because she's consistently the best girl in the series (crossdressing Wada being a close second). I'm a sucker for deadpan snark and Yuri could teach a class on it.
I agree with others in believing Yuri and Tomoko have better chemistry since the Asuka x Tomoko dynamic is basically one sided infatuation and Tomoko just being a wet mess of nerves. To put it bluntly, Asuka is way too hot for Tomoko to be an equal in that relationship and it is essentially the 10/10 hot girl dating the 3/10 dumpy nerd which while making for a "heartwarming" story about how true love is blind and anyone can find happiness does ring hollow when you consider that they have basically nothing in common and its driven just by lust.
That said, I don't actually see Yuri as having romantic feelings for Tomoko beyond maybe pushing the line of the female equivalent of a bromance. Yuri's only other friend in the series has gradually been downgraded to one of the worst characters (Mako is a self serving cunt and you can't convince me otherwise) and she's seemingly found a real friend in Tomoko who treats her as an equal without looking down on her despite the playful jabs they throw at each other. My interpretation is that she's just found an actual group of friends for once rather than being dependent on that bitch Mako who was never really interested in Yuri except out of some ill-conceived sense of moral superiority. Hell even Nemo is more of a friend to Yuri.
I guess what I'm ultimately saying is Mako sucks and the only reason Yuri x Tomoko is even up for consideration is because it's the first time Yuri has had someone who doesn't treat her as a chore or afterthought so she's leaning into it harder than normal.
