Service [Q] Is Stock 4.4.2 relatively safe and stable for Nexus 4?

I am among the last crew of US customers for the Nexus 4. Having seen lots of KitKat bug reports, I have been deliberately keeping my Nexus 4 at Android 4.2.2. (My phone is rooted but I have retained the stock ROM and I prefer to stick with stock versions for now.)

For those of you already using stock KitKat 4.4.2: Is your experience smooth? Has battery usage been consistent/better compared with previous Android versions? Would you recommend that I update? Or should I wait a bit longer?

(I also wonder how many interim updates I'll have to do if I go through the official OTA process.)
