I really like Skull's and Viper's design

I really love most of the character designs girls have, especially Bluebell's and Yuni's.
It saddens me that most of the women, minus Lal (even though she is still severely reduced to just crushing on Colonnello at the end), end up either needing saving from Tsuna or their previous personalities are just thrown out.
I also really like Byakuran's relationship with Bluebell as it pushes against the otherwise really formal relationship he has with his other guardians where they cannot refer to him without "-sama" or talk to him in an non formal way.
Yuni is a great character, following the characteristics of both her mother and grandmother who have chosen sacrifice over destroying the whole world for their own sakes.
A lot of the fandom hates Luce but doesn't put themselves in her shoes, cursed with the ability to see the future, would u rather sacrifice yourself and 6 other individuals to continue the cycle and give other humans chances to actually live and not perish instantly.
Not to mention she was probably already pregnant when she received Kawahiras orders to gather all of the cursed 7.
There's so much more to discuss but it's like people avoid the mention of what could've been of these characters.
