CallMeKevin, hands down. His videos in general always make me laugh and the Sims ones are no exception. Jim Pickens is my new favourite villain, and the sheer chaos that unravels in every episode is something you never really see in any other Sims videos. While I enjoy playing through my Sims 4 game with nice, normal families, I can't stand watching others do it (it's so boring to watch), which is probably the main reason I love Kevin's crazy weird family of vampire bears, prisoners, numerous Santa Clauses and whoever else is in there.
Also the fact that the Sims team patches exploits the moment Kevin abuses them is always hilarious.
