60Hz still looks great.
If you want the color you've grown accustomed to without the ghosting, then the Eizo Foris FG2421 would be what you want, as it is also a VA panel. However, it has a firmware level strobing and a 120Hz refresh rate, so it has virtually zero motion blur. It'll look better than your Plasma even.
tbf I don't even care TOO much about the color. Actually, my biggest problem with the monitor (besides the ghosting) is text is annoying to read (its almost like the screen door effect, but not exactly), and I think thats also a thing with the VA panel (either that or I'm just perma-fucked from using a retina MBP and a retina iPad haha), so I think it might be better if I just avoid a TN anyway.
