Id be interested in yours, too. I havent had much time with the ST60 yet, bear in mind.
The ST60 has better black levels. They are just there, they dont require tweaking to get them. The Samsung requires more tweaking to get them. And the issue with the white crush and needing to turn up the "backlight level" and contrast doesnt help.
The Samsung has a superior AR filter, though the ST60 is pretty good too. The Samsung also has higher light output, but the ST60 isnt bad in that department either.
The Samsung Smart Features are better and much more ergononomic to use. But I dont use either, I use Roku and Amazon Fire boxes. Samsung seems to have more processing power behind the Smart Features too, being very snappy. The Samsung has better integration with technology and connectivity.
Both have good ATSC tuners.
The ST60 is superior in a darkened room, but can handle a bright room. The Samsung with it's higher light output and superior AR filter is superior in a light polluted mess of a room (which I have it in, room with walls of windows on 3 sides) but still does very good at night there.
If I could only choose one, Id probably pick the ST60...because at the end of the day it's about picture quality and the black levels are just superior on the ST60 combined with it's still higher end for a plasma light output (2nd only to Samsung) and it's a better display (as opposed to gizmo wiztechery)
EDIT: The IR issue is neither here nor there. Both sets have variations in manufacturing and some units have to greater degrees than others in both models production runs. So not really an issue.
