I don't have a dog in this fight but these are some things I read a while back in case you haven't already seen these.
When it comes to picture quality, Samsung F8500 is a positive surprise – again. Samsung has made significant improvements to its plasma TVs in recent years and after many years of standing in the shadow of Panasonic, Samsung has finally stepped out and pretty much matches picture quality of Panasonic’s high-end plasma TVs. F8500 has amazing black levels, great color reproduction, great motion reproduction and far higher brightness than most plasma TVs today. The higher brightness is one of the clear advantages over Panasonic’s VT60 and makes Samsung F8500 better suited for brightly lit living rooms. Despite that, we still believe that Panasonic VT60 has the edge.
All in all, Samsung F8500 is a great plasma TV and one of the best TVs on the market right now. Some of the classic plasma problems remain and F8500 is more expensive than previous plasma TVs from Samsung, but F8500 is still an amazing TV that definitely deserves our Highly Recommended Award.
Value Electronics Flat-Panel Shootout Crowns Samsung F8500 "King of HDTV"
IIRC the shootout was between the more expesive Panasonic the VT60 and ZT60 and the Samsung F8500 ?
Panasonic ST60 is an amazing TV, let us just say that right away. But not for its many features or its design. In those departments it is a fairly average TV with a modern design but nothing spectacular and a Smart Viera platform that still leaves us wanting more, despite the revamp. No killer apps are available and even though there are some useful features, most new features are reserved for the higher-end models. At least we are not recommending ST60 based on the Smart Viera features.
But when it comes to picture quality it is an entirely different discussion. ST60 delivers 2D picture quality that you would expect from Panasonic’s high-end TVs just a few years ago. Black depth is simply amazing and approaching perfection, color reproduction is good and motion reproduction is exemplary. In fact, Panasonic’s more expensive high-end TVs could very well have one of the toughest competitors in its own ranks with ST60.
Some issues remain, such as dithering noise in colors, audible buzzing from the back side of the TV and a filter that is not as good as in some of the more expensive plasma TVs from Panasonic from the 2012 line-up, but that does not change the fact that Panasonic ST60 is one of the best value-for-money TVs we have seen to date and even one of the top-performing TVs. That is quite amazing and Panasonic ST60 receives our warmest recommendation.
If they are willing to give you the F8500 for what you paid for the E8000 I would seriously think about it and maybe take that offer just saying .
OTOH if they wanted more money then I might take the Panasonic ofc I would like view both sets first .
Are the ST 60 and the E8000 comparable to price you paid ?,if not will they credit you difference ?
Maybe some money back and the ST 60 wouldn't hurt either as I understand it the ST 60 is very good .
ofc that all depends on what you paid for your sammie if that is same as ST60 price ofc that is fair also.
A no charge exchange of the 2012 E8000 for the improved 2013 F8500 would
seem to be a fair offer I believe it uses a different (newer panel) just saying.
So far my 7 mo old Sammie ( 2012 model ) is doing fine.
In all fairness I did prefer the brighter (not necessarily better)
picture of the Sammie to the equivalent 2012 Panny ofc that was in
the store not best of places to compare .
that is just a preference of mine.
A 2013 VT60 / ZT60 ofc might be different
Maybe the VT60 / ZT60 are more equivalent to what you have ?
Will they give you one of those
Good luck I m sure either set is a good choice .
