you’re going about it all wrong. Don’t spends days looking at info from the people who market them to you. Go to a TV nerd forum and see what people with similar needs are buying / paying. AVSforum.com is a great place to start. Then go check one out and you’ll know why they are good or bad from the reviews instead of just staring blindly at spec sheets that have meaningless numbers for the most part.
also remember that unless you have florescent lighting in your living room, you can’t get a real idea how they are going to look anyway.
