I love plasma, but it's not good in a brighter room or if you're going to do a lot of daytime viewing, etc. LEDs are actually a great option and have come down in price quite a bit. 4K is probably not worth investing in at this point...there simply isn't much 4K content out there right now. Also, skip the curve TVs, if you're even considering them. As far as other brands, Panasonic is good and some people like Vizio. Samsung is really well regarded and a very safe option.
