720p vs 1080p: ANSWERED Now Samsung vs LG

This whole TV thing has become crazy.
I spent HOURS this weekend trying to decide what to buy.
It is impossible to compare sets because everyone makes theirs a little bit different.
I am quite sure the makers do this on purpose.
Crutchfield is starting to remove new tvs from their website because the newer, better tvs were cheaper!
I assume they are trying to “unload” the old stuff first.
My intension was to purchase last weekend but I refuse to invest in something that I don’t totally understand yet.
