Problems are often out of proportion on forums. I mean not many people post just to say, "Oh wow! What a great display!" except as side comment while discussing setup procedures, etc.
But people with problems do congregate to discuss the issues at hand. Of course, the threads are the longest on the most popular brands.
So I don't know what the real numbers are... if you go by CR they are crappier for Samsung than for Panasonic, etc. But not by huge amounts.
In any case, regardless of brand, I don't think I have 100% faith in any these days. And it is probably a good idea to have a Costco/Square Trade purchase and extended warranty for the best protection.
I chose VE for purchase because they did have them in stock and were new and factory sealed, while several other sets online were questionable. Plus, besides the pre Cal they offer, I think the 200 hr. break-in period before they even put your credit card through is an excellent service that could save more than a few people some grief early on.
