The best VN's I know of are these, some are developed by good friends of mine/our project!
What a Legend by Magic Nuts
Ravager by 4MinuteWarning
Leave2GetherAct2 by Leave2Gether (It's not ready yet and only has about an hour or gameplay)
Seeds of Chaos by Venus Noire
Knightly Passions by Feyada
There are a few more being worked on currently that will be released in the future and I'll recommend them when the teams are ready.
