[Q] Stock vs CM12? topic

Hi all. I have one question and I need a honest answer.
I currently have LG G2 d802 32gb version currently running stock kitkat.
I wait so badly on lollipop update but.. I was bored today and I found some videos in YouTube about CyanogenMod12 for LG G2 and now idk what to do.
I used a HTC Desire S for a long time running cm11 and I kinda miss Cyanogenmod hehe.

So the question is, should I root and get cm12 or wait for official lollipop?
Just to note, I'm not an Android hacker or anything like that and I dont need root to modify my phone in those terms.
I just know that cm really smooth is and I would like to know is there a big difference between stock and cm12?

I mostly use my phone for Internet browsing, Whatsapp and sometimes games.
Also I know I can do all of that with stock but still, I would like to know is it worth to flash cm12?

How's the camera, are there any big bugs and errors, how is the batery life etc.

Thanks for info. Cheers!
