In HS there is realistic visual style, in KK there is anime visual style. Here you have dialogue system to talk with any girl and make her like you (or hate you), and dialogues are differ depending on girl's personality and parameters (in HS there is no dialogue system). You have to please girl right to enable all poses and all holes for sex.

You can have sex on any location here (if girl likes you enough), and there are much more locations than in HS. Here you have full-fledged long story with several girls, but you are free to finish it with your own pace and have affairs with other girls. The mods are harder to add (and especially to remove), and they can often conflict with one another (even the ones for clothing parts and other stuff like this (and this happens often, when you have tons of clothing parts from mods))

Honey select basically has no story at all, just several rooms for sex, and almost no gameplay exept for pose changing and some 'emotions' mechanic (you can make them like you or hate you or break them morally, which affects their face expressions and voices).
