We've had it now for nearly a couple months, and at Deacon's prodding, I ought to give a good review of it. Or at least one reasonably mediocre enough to keep the CDC off my back. 
bscene-buttred:
Our unit is the 50" Vizio 4K TV, the P502ui-b1 (yeah, the model numbers are hard to remember). It's the small one of the family, purchased at Walmart for what was then a good price (under $900), since then I've seen them at Sam's Club for under $700 (where it's an outright steal, IMO).
Note: I have no idea how good the speakers sound in this thing. I don't use them at all (everything is routed through a Yamaha RX-V375 receiver to a 3.1 Klipsch Synergy F-1/C-1 setup with Klipsch and a Paradigm PDR-10).
Picture quality is OUTSTANDING. I know there's apparently some glitches in the thing based on professional reviews, I can't tell. I calibrated the set with the THX iOS app (nice and easy), and when fed a 4K feed from Netflix (the only 4K source I have is the smart TV streaming apps) the picture just jumps off the screen. It's simply amazing.
Feeding it a regular HD stream looks pretty darn nice too... if you've read the manual. One HDMI input is set aside for 4K/60Hz content; the manual tells you that to feed it anything non-4K into that input will result in a lesser quality picture. They aren't just whistling Dixie; stuff didn't look that great when I had it plugged in there. I changed the input and things got better. The internal TV scaler from HD to 4K is quite capable. I haven't tried feeding it a 480i signal; I do upscaling at the receiver for things like that. I simply can't find fault with this TV... I'm no display professional, but I've seen far worse and, in shopping around, the ones that cost 2x as much (or more) didn't look any better.
I did turn off all the motion smoothing abilities; they ended up making things just look weird. Disabled, it's more normal.
The remote control is probably the best one I've ever seen- a shame, since I use a Logitech Harmony (which controls it just fine). There's a QWERTY keyboard on the backside so it's very easy to use search features on the included TV apps. Even with the Harmony, I keep that remote handy just in case.
My only real gripe is the lack of any control buttons on the set itself. A power button is hidden around the back, but if you're standing at the set there's really no way to change inputs or anything short of going and grabbing the remote.
So, would I recommend this thing? Absolutely. If my Mitsubishi DLP bit the dust I'd be buying the 65" version of this thing. I don't think you'd get anything with any decent quality for less and I also don't think you'd get much more if you paid more.
