[Verizon Samsung Galaxy S III] TechSavvy2:
I followed all my squeaky clean wipe as I posted before with fix permissions and all....

The good:

Phone seems much much quicker than Beta 3. It may just be individual components, but overall I can make it just GO now....even while multitasking. I can literally flip through home screens that are full of widgets as fast as I possibly can and I still can't make it twitch, it can go faster than I can.

The annoying keyboard lag we had before is improved. Its VERY quick right out of the gate when going through the setup procedures, however ever so slightly dips in performance after that. You have to type extremely fast to even notice what I'm referring to. It may even just be the stock samsung keyboard, I haven't tested the others yet as I'm only testing what's packaged in the rom.

The external-sdcard used to take a decent amount of time to mount properly before. Like a good 5-10 minutes sometimes. If you went through setup and immediately opened a "working" gallery before, you'd notice your stuff wasn't there for quite some time previously. This is all completely working good now. It is instantaneous now.

Obviously the wallpaper/gallery issue is fixed (still) as it was also fixed for me in Beta 3 but "some" users claimed for it to still not work. It works fine (again, still).

I don't remember if it was an issue in this rom or CM since I use both religously, but when recording video and then replaying it, the volume works as it should now. Full sound output through video playback. Camera and video taking both work great. Even great image quality (versus the crap quality on the stock tw ics build)

Phone actually seems to spend more time in different cpu states than it did before. I noticed a significant amount of time in 1512 before whereas now, while still obviously in 1512 a lot cuz I'm messing with everything so much right now, it actually flows through usage in different states also. It even hit deep sleep a couple times.:)

The bad:

I usually don't like to report it cuz its almost just as likely to be regular tw behavior - but I had one random hot reboot. It was from nothing either. Phone sat idle, screen turned off like normal, but when i went to turn it back on, it just vibrated a couple times then rebooted. NOTE - I really don't think this is necessarily something that's relevant specifically to this rom as it happened right out of the box stock for me. Its rare and only has happened once in a while, but every build of every rom will have one here and there.

Phone may (only potentially) get a little warm. However, only noticed when on a charger. I know from many phones and many "toasty" kernel experiences how hot it should and shouldn't get, and this is only similar to the equivalent of phone running at supersonic speeds and charging rather quickly. Yes its warm, but not too warm (yet, afaik)

The unusually bad (probably needs the most attention):

GPS Status - does not seem to see anything at all. Absolutely zero. Upon further inspection, it isn't even trying to find anything. The usual blinking dot in the corner when its searching for gps doesn't exist at all. Ever. Even ran through some clearing google framework services data, clearing cache and data for gps status and maps etc etc and still nothing. Absolutely zilch. Its almost like the gps functions were just completely removed altogether. Whatever is going on here with GPS also seems to be chewing through a little bit of battery also as its second highest on my battery usage list after gps has been off and killed for quite some time now - Someone correct me if I'm wrong here, but I've always been able to troubleshoot any gps issues I've had into working correctly. Not this time.

Bluetooth audio - this is a main culprit of the "phone orgasm" random vibrations we've seen in past builds. Google Play music works fine in regular mode. It connects perfectly and flawlessly to the two bluetooth devices I've tested on. However, after I've connected it and try to play something, it FREAKS OUT, freezes, twitches, vibrates a bunch, gives errors, no music output whatsoever. - Specifically, this is when we get repeated, over and over, "shell has been granted superuser permissions" literally over and over and over and over. And errors of "Music Playback Error" in the notification bar.

Overall:

Definately a daily driver by my standards IFF you don't care about GPS or bluetooth, everything works flawlessly. Speed is actually quicker than AOSP currently (which always surprises me) :)

Hope this helps. Will report back more later.

EDIT:

And I also LOVE how the setup restoring apps from google account actually automatically works for this. Starts up so fast that I don't even have a chance to connect to WiFi before 5 or 10 apps are downloaded. Some roms don't restore and its a PITA for crack-flashers such as myself as with my clean installs I don't like to restore anything from titanium except data for downloaded apps.

EDIT 2:

Okay, hot reboot has actually happened three times now. All have been when simply turning the screen on from idle.
