You can search threads for specific terms like "bleed" and "contouring"....
I don't have an ST60, but FWIW, here are some comments from reviews:CNET TC-P55ST60 Review
"I... noticed what appeared to be slightly smoother gradations on the ST60 [than on the ST50]. At the 22:09 mark during 'Tree of Life,' the fading light from a white galaxy appeared smoother on the ST60 (and the Sony LCD) than on any of the other plasmas (including the S60), which showed visible gradation steps of minor 'false contouring' or solarization. Many other similar images in this sequence of 'ToL' did show visible gradations on the ST60 as well; however, they're rare in other program material on any display."HDJ Chad B TC-P50ST60 Review
"Skin tones had excellent color, though the ST60's handling of brightly lit faces reminded me of the GT50's rendition in THX Cinema mode: some shadings were not quite natural. This, I suspect, is a byproduct of the slightly fussy calibration behavior, which I am hoping was due to insufficient break in time. Regardless, it was minor and the overall presentation was extremely good."HDTVtest TX-P42ST60 (UK Model) Review
"The only downside related to Panasonic’s sub-field drive method is that certain combinations of colour and tone, if moved fast enough, can result in some false contouring... but it’s rare, and we still prefer it overall to the noisier but more temporally consistent panel drive mode used by Pioneer’s Kuro plasma TVs... Incidentally, line bleed seems to be reduced compared to last year’s ST50... We say 'seems to be' because our comparison here is our resident TX-P50ST50, and the larger size, and indeed individual panel, could account for the difference. Nevertheless, we fed both screens simultaneously with our custom line bleed detection pattern, and the effect was considerably lessened on the ST60."FlatpanelsHD TX-P50ST50B (UK Model) Review
"False contouring is still an issue... No improvements were found in this area compared to last year’s models (VT60 might change that, but ST60 does not).AVForums TX-P50GT60B (UK Model) Review
"As for all the issues that have been reported about Panasonic plasmas in previous years, almost none were in evidence. Problems like floating blacks, brightness pops and green blobs can all be consigned to history, as can the 50Hz bug of which we saw no evidence. Screen uniformity was also excellent, as evidenced by the ANSI measurements and confirmed using full screen rasters. There were also no problems with image retention, line bleed or dirty screen effect. There was some very minor noise in parts of the picture just above black but these were impossible to see from any sensible viewing distance. In fact the only issue that we had the P50GT60's image was that very occasionally we saw some dynamic false contouring. This tended to be on handheld footage where peoples' faces were filling the screen and you would see some contouring on their cheeks or foreheads."
