What makes them great? Input lag? Other brands have very good input lag as well.
Lack of lag and lack of any unneeded processing on the inputs by default. Too many cheap TVs leave all sorts of "enhancement" on by default with no easy way to turn off whatever interpolation, dynamic contrast, etc. that they think will help the TV sell. There can be exceptions of course, but recently almost any Sony has these characteristics so you don't have to research on AV Forums beforehand.
