3360 vs 3988 vs 3366 sensor

If you’re stuck between the 3360, 3366, and the 3988 then consider that the 3366 is the primal choice if low variance is your priority, and the 3366 is also better at max tracking speed than the 3988 - albeit few may go above 7m/s for gaming. However, technically speaking the 3988 remains superior in power and processing FPS at higher speeds. For using the 3988, it's approximately 4m/s at 1550cpi and below, adn 8m/s reaching 1600 and 3150, and then 16m/s at any cpi above 3200. Ultimately, 3988 is considered second "best" based on accuracy capability, features, and based imaging on specs. It is definitely comparable to the 9700/9500 as far as specs goes, but the 3366 was also built with a very advanced, and comparably stronger sensor architecture as outlined above.
