from my experience there are some bad apples in both laser and optical classes.
I wouldn't say either tech is the better pic. Most mice (both optical and laser) at their max cpi ... will produce some "jitter" or erratic behaviors because their true cpi has been multiplied several times.
When xim gaming .. the max dpi/cpi isn't always the best solution for accuracy and control.
Often on my xim's I'll pick the highest dpi and work my way back until I fell less jittery movements. which usually is far below the max speed of the mouse.
