I have a decision to make and I am not sure which to pick. 60GT50 or PN64D8000-7000

Nobody can really tell you which one fits your needs and requirements etc. You have to weigh the pros and cons of each model and decide what features and abilities you absolutely must have, and what cons you absolutely will not settle for, then make your own informed decision based on the data. The answer will be in the details of each models discussion threads.

Go Big!!! I have the 64d7000 and love it. The pic quality is great.

I bought a Samsung 59D7000 when it first came out, a year and half ago. Loved the tv, but to make a long story short, the tv died and due to the cost to fix, I decided to replace the tv. I bought a Panasonic 60GT50, and the this set is awesome! The biggest difference to me was the slight increase in depth & detail in the picture quality. I think this is due to the excellent black levels. I will say the Samsung was slightly better with 3D, but that is not really important to me, but I do enjoy it from time to time. Good Luck!

Did you really mean the d7000 and 8000 or the e?

Go with he largest screen plasma tech can offer the 64" Sammy or 65" Panny.
Buyers remorse can happen from knowing their is a larger screen but you went
with the smaller one when price was not an issue.

Don't buy last years model.
this years E8000 has an improved panel.
If you want to save $ you could go with the E6500 60", has the same glass as the E8000.

Def choose quality over size, i.e. don't buy last years models because they are bigger.
I am in the same boat as you right now, is the gt50 worth extra money over the e6500.

It depends on what's important to you - the Samsungs are said to be sharper and more detailed with 720p content than the 2012 Panasonics are and have better processing. Samsung's colors are not quite as good Panasonics, but he biggest difference would be Panasonic has much better black levels and much higher contrast which is very important to most people especially if they watch a lot of movies. Sports though kinda narrows the gap between the two brands.

Last year's Samsungs were solid performers, but there are some people in the Samsung threads that think the 2012 E series falls a little short of last yers D series. All of last year's and this year's Panasonic and Samsung models have one or more issues so there is no all around perfect TV right now.

My Sammy died too!! I will never buy that brand again. I had the Sammy unc7000. Not even going into the clouding problem with the backlight...the tv broke down on me 2x!!!! While my panny 850u which is 3 yrs old and NEVER given me a problem (knock knock knock) stay the F&$k away from from Samsung!! That's my advice!
