These roms are based off a leaked rom containing Manila 2017. They are a little buggy right now, but day by day, they will become more popular and eventually become the new standard. So far, they seem to be built a little better and function more smoothly, but it depends on your device, configuration, apps, and cabs that you install. My advice, backup your phone and give it a try. If you don't like it, restore the backup. Just be sure you install cabs one at a time to be sure they don't break anything. XDA-UC (and the like) may not be the best thing(s) to use right now.
