So I went ahead and flashed CM 11M2. I am in absolute love. Kitkat is simply amazing. I have not ran into any bugs at all. My music used to hiccup on all other ROMs, no hiccups so far. I believe it's the better memory management. Based on current usage, I should get over 3 hours of screen on time on the stock kernel. That's insane, that's what I was getting on 4.1.2 TW with the KT747 kernel (sinoclever). I don't miss TouchWiz the slightest bit.
