Default [Q] Custom 4.4.4?

hello,

I've been wondering how custom 4.4.4 roms on the Moto G fare these days. I'd rather stay away from CM, AOKP and the like for now, since Motorola's software is not bloated at all, we're all @ 4.4.4 and I'm not particularly ideologically inclined to go with open software, and I've seen there are still some small bugs. however, since I'll be rooting my device and wiping it anyway, I might as well go with custom stock. are there any interesting options? first of all, I'm interested in stability, no more bugs than vanilla stock permitted. second would be size and the ability to move the backup to OTG USB pendrive, and third would be battery life tweaks, OCing and extra addons (like pie). Could someone tell me how good are current options?
