Cyanogenmod vs 4.3 stock

What should I use? Stock 4.3 or root it and get cyanogenmod 10.1.3 on there?  4.3 has trim. Does cyanogenmod have a good garbage collector? 

Cyanogenmod all the way!!!!   i didn't get this though.: "Does cyanogenmod have a good garbage collector"... trim is nice though..

Another option would be AOKP and if you want customizability look towards Paranoid Android. If you are really stuck try the Packman rom which just all the features put together. Of course all are subject to availability.

or miui  =P

Paranoid android with HALO and PIE controls is a dream, the amount of extra usable screen space you get almost makes it feel like a brand new phone.
