LCD LED or PLASMA?

I have had a Samsung plasma for a couple years now and it is great. We also have a newer Panasonic plasma and it is nice too but not as nice as the Samsung. Both rooms don't have a lot of natural light shining on them through the day so reflection off the glass isn't a problem. The nice thing with a plasma is that when viewing at an angle it still looks great. I am not sure about the LED;s but the LCD's always seemed to dim as you moved off center to me.
