Choosing a new TV from 3 alternatives

by Panco90 - 2/27/12 2:45 PM

Hey guys, I'm in need for a new TV, since my Pansonic is reaaaly old. Basically, I've narrowed my alternatives to 3, prety much. These are:

Sony KDL-40EX720
Samsung UE40D6500
LG 42LW4500

I'm mostly interested in high picture contrast/quality, highly functional 3D is a bonus, but not a highest priority.

Which one of these would you recommend and why?
Thanks a lot.
