Strange, most plasmas I see are cheaper than LCD.
My friend has a SONY led lcd, the glass on it is as reflective as my plasma. My computer screens have matte finish and I would hate that for my movie display. Anywho, consumers in general probably think LCD is better because it is newer and more expensive. It's weird but that's just how people are, if item A is more expensive than item B, people assume it's better....or why else would it be more expensive.
I backlit my tv with rope light, it helps to lessen the reflections.
