samsung brand beats all of them
sony and lg is good at making it but their software such as smart tv is not very reliable.
and also depend on your room if you plan to put your tv in place where there no sunlight shine on it then get a plasma. just because plasma had more refresh rate and better picture quality than led, so when you do some gaming stuff, it wont affect.
other wise i would not recomment led because they had low refresh rate (refresh rate is Hz).
i owned a plasma samsung smart 3d . it is 51 inches and having 600 hz refresh rate
however, my tv's processor is old and it takes quiet long time to run smart feature.
with the samsung model you asked above, it will do great smart feature , however, the gaming will not work with it.
