That's obvious. All manufacturers will promote the settings that result in the best sales - that applies to plasma to. But the same applies to plasma. Unless you're trying to tell me that plasma manufacturers want their TVs to look crap to customers?

Again, I dispute that. Plasmas are cheaper, have excellent contrast and viewing angles. But the picture isn't as sharp and movement doesn't look as natural (despite the higher refresh rates).

LED HDTVs have come down in price nowadays, having better brightness and comparable viewing angles; they also now have better black levels. I have a 42" LED 100Hz TV attached to my computer and a 47" LED 3DTV in my main room - both were top end models. I compared the picture quality of both directly to the plasma models on display - from the cheapest to the most expensive - and they were both noticeably better. We can each pull out particular models that have advantages over the competing technology but my purchasing decisions are based explicitly on quality, not price.
