One reason could be that N type MOSFET can switch loads that are in Drain, meaning that whatever the load voltage, you can turn it on/off directly with any microcontroller, provided that the MOSFET is 5V or 3.3V logic level. You could invert it and do the same, but N-Channel just feels more natural, since it shares common ground.- Furthermore, going into design details, N-Channel MOSFETS have faster switching due to [higher electron-hole mobility](https://www.intechopen.com/chapters/54729).
- Due to this, P-Channel MOSFETS have a higher resistance when fully on.
- Presumably these characteristics lead to N-Channel being more common.
