I would MUCH prefer a 4.4 ROM over the 4.4 OTA. No bloatware and all the extra options. No doubt that we'll be rolling in 4.4 ROMs in short order
I also figured out the answer to my own question in another post: "What happens if my phone gets the 4.4 OTA in Stock Slot while I'm on the Slot 1 ROM? Will it break root and destroy all my work?"
The answer is NO. The OS in the Stock Slot is essentially inactive... it can't accept an OTA any more than a phone that's turned off can. So let the OTAs come & go... I'm blissfully ROMmed and rocking this thing like never before!
