CM is the BEST.
Super smooth interface (Project Butter really works)
Lot more customization options than TW
Every app works flawlessly
Awesome battery backup (i get more than a day of backup with WiFi on all the time and screen time of 4-5 hours on an average)
and most importantly its ANDROID 4.4 KITKAT
Camera is not that good when compared to stock
and for Stock - it always hanged for me, lot of ram consumption and not so good looking interface and all the samsung apps and features are more of gimmick to me as i did not use them much.
Thanks to pawitp for this great rom.
