[Verizon LG G3] altwu:
about a week ago, i finally upgraded to 47a. previously, i was running jasmine 4.0 + skydragon kernel. that setup worked great for a long time, but then issues started to pop up. rather than redo the install, i decided to upgrade to the 47a rom provided by [MENTION=2941286]xdabbeb[/MENTION]. i wanted a clean, fresh install so i followed all the instructions on this forum to revert to 10b, root, and then install 47a. since jasmine 4.0 is a 12b based rom, reverting to 10b wasn't necessary. i did it because i wanted a clean, fresh rom install. here are some of the things i learned along the way and after a week of use. my experience may be different from others.

while going through the phone setup after reverting to 10b, i skipped any email account(google or other) setup. since i was going back to 10b for the sole purpose of gaining root and installing twrp in order to be able to flash 47a, doing any account wasn't necessary. i rooted with stump. ioroot should work also. the downside to this was that i couldn't download flashify or twrp manager from the play store to use to flash twrp. since i didn't have the apks for those apps, my only option for flashing twrp was via adb as described here.

after flashing the 35b bootstack in recovery, i rebooted back into recovery as suggested by [MENTION=3522545]mopartonyg[/MENTION] here. after that, i flashed the 47a rom, debloat scripts, and hotspot mod. some have had success flashing everything all at once, but when i did that, i didn't have root. i don't think it hurts to reboot into recovery after flashing the bootstack and it adds only about 30 seconds to the upgrade process.

i implemented the external sd card fix described by [MENTION=4888382]Robshr[/MENTION] here. there's also an app that will make the same changes.

even with the external sd card fix, titanium backup wouldn't write to my external sd card. i had 2 options to get around this: 1) backup to internal storage and then copy to the external sd or 2) use the DocumentProvider storage option in titanium backup to get it to write to the external sd card. i opted for #1. one time i tried DocumentProvider storage and i got a message saying that titanium backup was moving the backups and somehow they got corrupted.

even with the new doze feature, my battery was draining quickly. greenify put a stop to that.

overall performance has been good. gaming performance isn't as good as what i had with jasmine 4.0 + skydragon kernel. the os still needs some tuning. i have a thread about it here.

i use google hangouts for text messaging and it had problems downloading mms messages. it turned out that pushbullet's sms sync was the problem. disabling this allowed me to receive mms messages again, but i didn't have this problem with jasmine 4.0.

April 20, 2016 UPDATE: After a few weeks of use, here are some other things i observed/experienced.

the rom is very snappy. it's much more responsive than KK. i'm guessing that a lot of this is due to the change to android runtime(ART) vs the dalvik virtual machine. my antutu ux benchmark score was almost 2x the score i got with jasmine. other benchmarks weren't as good though and performance in the games i play still isn't as good. more details in the 47a performance q&a thread.

the material design is nice. i like the window shade animation for notifications and the animation for recent apps. the newer lg weather app is nice too.

on jasmine 4.0, i had a problem with google play music not working well with bluetooth. it kept killing the bluetooth connection. the stock lg music player didn't have this problem. after upgrading to 47a, this problem is gone so i can use google play music once again.

i encountered another issue with the external sd card. the stock lg file manager writes to the external sd card just fine. the workaround for titanium backup to get it to write to an external sd card without using DocumentProvider storage works great. i also have root explorer and it can't write to the external sd card without setting up something that's similar to titanium backup's DocumentProvider storage option. any sort of preprocessing vs. direct filesystem access makes me nervous about corruption. this security "feature" that restricts apps' write permissions to only their directory under Android/data is a pain.

imo, 47a isn't a slam dunk win. some things are better but there still some annoyances too. gotta take the bad with the good, i guess.

i hope this is helpful. again, my experience may be different from what others have seen.
