Just a matter of different people have different views on what looks good to them.
Hell, even I am not really a videophile like most on here. I've never spent more than $1000 on a TV (just got the 55" UT50 for $850), would never pay for calibration etc. I only went plasma this time as I just couldn't find any well reviewed LED/LCD sets for under $1,000. I started thinking of upgrading when saying an $850 deal for a 55" Panny LED. But it wasn't 3D and reviews were pretty bad on it, so I ended up going with the plasma when I found that sale since it was reviewed as one of the best TVs in that price range and has 3D.
I like the better blacks etc. on the plasma for sure. But I'd have passed on them for no IR worries or buzz if there was a well reviewed 55" LED set the same price. But they just aren't there yet price wise, so the plasma was the best option in my budget right now. I'll reassess down the road when an upgrade is needed--and that will be a while unless this one dies.
