There are a few, just a few, high end plasma TVs still out there that offer picture quality that is equal to or better than the best LED/LCDs.
Couple other small reasons. Plasma's 'refresh' rate (which is an inaccurate statement in itself, it's really phase change) can not match LCD's (LED is still LCD, its just LED backlighting instead of fluorescent). So you don't see 120hz/240hz stuff on plasma's (which many do not like anyway). Also, for the same reason, 3d is generally better on LCD (not that I care).
The main reasons plasma is superior in pure picture quality though is simple:
1) LCD's use a square pixel grid, plasma cells are round (or more complex polygons), so curves and so forth look more natural on plasma.
2) Plasma's create their own light. Each cell produces light, whereas LCD's have a backlight. So even when an LCD pixel is 'off' light is still leaking through from behind. When a plasma cell is 'off', its off. This makes for dramatically improved contrast and black levels.
They both have their advantages for different reasons, but if you are looking for pure image quality (especially still frame) you can't beat plasma.
