I'm surprised you aren't recommending the Samsung F8500 given the closeout pricing. While the final Kuro Pro models have slightly lower black levels (particularly if you luck out with one of the 'magical' ones with the voltage set different), but the Sammy is still as black as pretty much anything else released that isn't an OLED. Plus it has better contrast, whiter whites, bright room performance, and far more features (interpolation, 3D, DNLA, apps, etc).
Not that I'd turn down a Kuro by any means, but since you can grab a F8500 new at crazy low prices ... seems like a reasonable alternative.

The Samsung F8500 tied overall with the current LG OLED (9300) at the annual HDTV shootout (this is a side-by-side comparison on a variety of categories ... all sets are calibrated and rated by professional calibrators ... and there is a second group of 'laymen' that also vote).

Also, c-net's reviewers place the Sammy only behind the LG based on their internal reviewers. The year prior, we saw similarly close ratings when looking at the prior models (with Samsung's OLED and Panasonic's VT/ZT Plasma in the mix). Basically it's been OLED/Plasma > LCD since OLED hit.
Regardless stating it destroys Plasma can only be attributed to you having not viewed a calibrated high-end Plasma. Obviously not all Plasma are of that caliber. Of note here as well, the Sammy can be had for like a 1/3 of the price of the LG (and has 3 sizes).
Ah that confirms it - you haven't seen a high-end Plasma. Modern 600Hz Plasma that use newer phosphor designs do not have green trails (that issue was due to a longer decay time in the green phosphor).
OLED does have objectively lower temporal (motion) resolution due to it using sample-and-hold like LCD's. Thankfully its response times means no added physical blurring like LCD, but its display method does inherently lower temporal resolution versus Plasma unless interpolation is used. Obviously whether that bothers you is a personal question.
Regarding the LG, it actually has some weird motion issues ... but I suspect that is either a firmware issue or potentially part of the panel drive system. I have no reason to assume it's systemic to OLED itself, but it's unknown when or if LG can fix it on the 9300. To be honest, I'm looking forward to LG OEMing panels to companies like Sony, etc. LG, regardless of their fabrication prowess, has never really had all that great of a record for image processing and the like.
