I didn't stay on it for very long. I restored to my backup a few minutes after confirming it was still 4.4.2. I would have had to do a full factory reset to really see if there were significant changes, as Odin kept my /data untouched. I might play around with it some more when I have more time.
I'm curious too but doubtful that there'd be anything significant. From 4.4.2 to 4.4.3 and then to 4.4.4 there weren't any notable cosmetic changes on stock android to begin with other than tweaks to dialer and contacts (which don't matter on thsi tablet). Most of the change comes in the form of bug fixes and security patches I would think.
I suppose its possible samsung did their own touchwiz tweaks at the same time but my experience has been that they enjoy letting current owners envy those lucky enough to purchase newer devices. A classic example is how Note 10.1 2014 edition owners had to wait until well after the Note Pro release before they could get their Kitkat update. A manufacturer never wants a software update for an existing device to steal the thunder from a newly released piece of hardware.
We'll see if other regions get this update. If all regions get ANG2, then I might reset my tablet and start from scratch with that firmware version. I should have checked to see if it had fixed that nasty Chromecast systemUI crash.
