Default [Q]ZRam - Enable or Disable? (CM10.1)

Hello,
I'm using now CM10.1 ROM (Lenio vQuattro by alin.p) and I see in tips to enable ZRam.
I read many threads which saying to disable it, because it's useless and battery drain.
So I'm really confused....
Should I enable or disable ZRam? (I'm facing more on battery life)

Thanks in advance.
