Nono was the best. Too bad she's not on the list. ._.
Kurenai seems to be the best example of a good, single mother- but she's not on your list either.
Kushina and Karura (Gaara's mother) were great despite dying in a very short time after- they instilled their children with love.
Yoshino seems like a strict average mom.
Karui and Ino seem like decent, strict moms out of the Gaiden generation of parents.
Kaguya, Mikoto, Orochimaru, etc were pretty terrible. No thanks.
Karin and Mito we know absolutely nothing about as far as their parenting goes. Karin hasn't been around, but the reason should be given in upcoming chapters.
Adult Sarada/ChoCho is a troll. Nice lol.
I'll just vote for Hinata since she seems to be the most gentle/kind mother out of the Gaiden generation.
