At some point, grain starts to look like image detail, so 500T can give the illusion of more detail when it's just more grain. And if the grain is in sharp focus, we tend to think the image is sharper.

Tungsten stock just has a faster, i.e. grainier, blue record (yellow dye layer) to compensate for the lack of blue wavelengths in tungsten light. Not sure if that would contribute to increased sharpness over daylight stocks.

I think the 50D stock doesn't have a mix of fast and slow grains since it doesn't need the fast layer, but you'd think that would make the layers thinner and thus improve sharpness.  Perhaps the extra sharpness of 200T was simply a design issue since it was the most common stock used for chroma key work.
