Their motion clarity and uniformity will be nowhere near that 2011 plasma. I would much much rather have a 2011 plasma for anything dark or with action.
I would only buy an edge lit tv for two reasons:
1. I am a gamer and the tv will play games 90% of the time and the input lag on a set is low.
2. I am a father and I am getting a cheap tv for a kids room/playroom (Aka I will never watch it).
If you are buying a TV for you to watch tv/movies and you can't afford OLED (by far the best technology) then at least get something FALD. Edge lit is garbage technology meant to prey on consumer vanity and brand loyalty.
Coincidentally, I think my low end plasma, which is an LG 42PJ550 1024x768 16:9 60 Hz HDMI model, is circa 2010, and I bought it for something like CAD$549 in 2011. Black levels are great, and contrast is too. The brightness isn't the greatest for bright daytime viewing, but really the main major gripes with it are just the uber glossy screen and the fact it's not a 47-48" TV. Lots of reflections and ambient in the daytime because I've got big windows. At night I'm perfectly happy with it. No reflections (unless the fireplace is going), and just the right level of brightness. I do have another smaller gripe with it though. Since it's roughly 720p, even though I'm at 12-13' seating distance, I do sometimes see problems in text on-screen. However, a 1080p set would likely solve that problem, and for TV and movies, the 720p doesn't bother me since it looks decent. Hell, even 480p DVD looks quite OK on that size TV from that seating distance.
The colours were quite a bit off out of the box, and this is one common problem I've noticed with a lot of cheaper TVs, but once I calibrated it, it looked very decent. Way better than the CCFL LCD that it replaced, that I paid more than twice as much for a few years earlier.
This is not my home theatre TV though. I do watch a lot of TV on it in the living room, but my movie TV is the home theatre projector.
I think I'm going to keep the plasma for now. I'm now looking more for my home theatre, since the existing LEDs would actually be a significantly improvement. Seating distance is close, and I'm using a projector with not very great contrast, and one where the iris is starting to do funny things occasionally.

The other problem is that my home theatre isn't 100% light controlled, so during the day everything looks washed out.
Luckily(?) there is only one implementation of an OLED TV on the market, so if someone goes to the store intending to buy an "OLED TV" they can't fail. Maybe one day there will be other OLEDs and some of those might suck, but I would love to have that problem. I hate the lack of competition in the space.
I saw an OLED in the store the other day and it was absolutely spectacular. However, it's just way, way, way too much money. Just like I avoided $20000 plasmas when they came out, I'm going to avoid $10000 OLEDs now.
And my wife doesn't seem to keen on my going down-spec for a 65" TV. She feels that's too much of a drop from our 90" projector image in the home theatre. So, I'm still aiming for 70" to 75".
