Well quality has many aspects, like Brightness, Sharpness, Detail, Color Fidelity, Uniformity.
Normally, an imager with higher pixel count will give you better sharpness and more detail, but lower brightness.
Color Fideltiy is more an issue of image algorithm and lens, not much related to image sensor.
While the phones are having 100M pixels, most of game cameras are still stuck with 2MP/3MP/5MP imagers,
why? Because of the game camera makers could not solve the brightness problems for black IR cameras.
But there are some cameras that are using 8MP/14MP imagers that give much more detail and sharpness.
And, even two cameras with the same MP image sensors, may not give you the same quality.
Because software and DSP play a big role in image quality, so the maker's capability is important.
Most of 20MP cameras on the market are interpolated from a 3MP imager with a software stretch of
20/3 = 6.67x, way too much. On the other hand, if stretch a 5MP into a 24MP, the stretch is only 24/5 = 4.8,
more acceptable. Now, even if two cameras have the same stretch, the quality is again different from vendor
