Since there are so many Nagatoro comparisons, I'll add mine.
Nagatoro (post vol 1), teases Senpai when he quits at something. It's like a sadistic form of encouragement. When Senpai puts his passion into something, she's proud of him. She still tells him he's gross, but she's said it so many times it's a term of endearment by now. (Also, she's laughing and smiling, not serious)
Uzaki runs down her senpai when he tries new things (cat cafe, bouldering), then acts like a brat if she loses, EVEN if she's in the wrong. Uzaki is more petty than anything.
Nagatoro can apologize too.
