Mods Or No Mods?

I love the game without mods! I used mods and CC heavily in TS2 and TS3, and it eventually made my game feel messy, and it was sometimes buggy and would slow down my computer/gameplay. I realize that mods and CC for TS4 may not have this same effect, but I don't know, I don't run into so many glitches in my game that others report, and I love the game as it is. I do have all the DLC so that could be why I feel like my game is complete and CC/mods are unnecessary.

I have read some people's testimonies on MCCC that tempt me to use it to customize the lifespan... but that will open up a black hole for me lol.
