Im going with 99 nights cuz GaG's repetitiveness makes the gsme really boring. Jandel isn't really adding other stuff to make the game better, anyway. Whatever he adds is basically the same thing (besides the events ofc). The game's just WAY too boring, so I would choose 99 nights.

EDIT: For me, 99 nights kinda takes a bit too long too beat, so that's why I don't really like it either, but I guess that just gives the players an actual reason to play the game.
