I tried MCCC once, but then decided to play vanilla, because it's easier and I don't have a huge need for mods. I play rotationally, have many packs, explore them slowly and have only played TS4 for two years now, so there are still many things I haven't experienced in my play.
I might try mods or cc later, but at the moment I just don't need them, though some of them look cool. I have especially considered the mod for a smaller mosaic/censor, because then I could take better pictures of my sims and they would still be appropriate.
