Samsung has made glasses lens optical quality NXG-3DG do not. A detail very, very small (like the "noise" in the plots) is lost when using glasses NXG-3DG. Should I buy more if I needed glasses above Samsung? Yes! However, if they are the same price I would buy glasses from Samsung.
Also, they suffer the same intermittent losing sync (flashing) as the Samsung glasses. It is not constant enough to be annoying, but there are DIY fixes such as the tape method if you Google the issue; if it happens to annoy you. Unfortunately I cannot comment on the coolness factor as both styles glasses have made me burst into uncontrollable laughter when trying to have a conversation with someone wearing them; seriously don't go out in public with these or the Samsung glasses unless it's Halloween and you have a pocket protector.
My vision impaired, spectacle wearing dad prefers these over the Samsung glasses as they fit nicely over his actual glasses. Apparently they are more comfortable. My very petite girlfriend likes the Samsung glasses better as they don't slide down her nose as often as the Nxg-3d glasses (realistically I am getting her the Samsung children glasses as those should fit her better anyways, but if Nxg made kids glasses I would buy those as they would be close to 3 times cheaper!).
Bottom line: 3D is very fun to watch! And less money = awesome. As a side note, I tend to wear those glasses more often than Samsung as I usually do not put things where they go and NXG-3DG glasses are at hand as I was heavily on their peer review is not when I had ordered.
They also have an auto shut off feature and the ear pieces are flexible which gives me a greater sense of ruggedness than the Samsung glasses (that I tend to "serve" to people with a sense of great care on a protective platter with a list of instructions and a laynard so they don't drop and break...), so kids and guests have at, the Nxg-3Dg glasses make my 2000 dollar tv purchase easily stay within a less jaw dropping price than what I originally thought it was going to cost just to watch 3d!!!
