Plasmas used to be a bit behind in terms of resolution, but that was quite a while ago. Thanks to advancements in technology, plasmas have now caught up to LCD's in terms of resolution. Having worked around all three brands listed (as well as both plasma and LCD), I can safely say that all of them are on par with each other. If you are going for the LCD no questions asked, I'd straight away go for the Samsung LED LCD due to the LED backlighting technology. If I was to choose a TV for myself though, I'd be going for the Plasma but this is because plasma has just that slight advantage with the contrast ratio and I do most of my TV watching at night where the plasma performs its best. That said, LED TV's are getting damn close on the contrast ratio side of things. My recommendation though that covers most situations would be a LED TV, and from the Samsung LED LCD you have listed... you can't go wrong. Another bonus with this is the fact that an LCD usually works out to be more space efficient than a plasma... and LED TV's are even better.
