I counter-disagree ;)
Laser sensors tend to have inherent hardware acceleration, angle snapping, jitter, prediction, Z-axis issues, etc
They are also very very finicky about the surfaces they use, or else the issues get much worse.
All the issues above? Optical sensors don't tend to have. I would ask you to clarify your use of the word "accurate" in addition. Are your referring to some of them having a higher resolution or being able to attain a higher DPI?
These days some laser sensors are more refined, and the difference is less. Some laser mice can be better than some optical mice, but optical mice just tend to be better. There's no reason to pay the same for a slightly inferior sensor.
