I just noticed there is a poll on the LoP blog (http://lopteam.blogspot.fr/). I voted and I just wanted to explain my vote briefly.
I chose Lake Party and the main reason for this vote is because I liked how you "steal" the girlfriend (wife would have been just as good) of one of the other male NPC. An other important reason is because I really prefer to play a male character. Finally the game offered two girls instead of just one in some games. Game mechanics were not really involved in my choice because I think all the games in the poll have simple mechanics (I like finding and using items though !).
If you voted too, let the developpers know why !
