(Newbie Question) What Rx Modulation is used for which flying vehicles?

#1
So I know there are different modulations like PWM and PCM ect, iBus and Sbus...
I've read the differences between them and understand how they differ, but I didn't see any information on which is best for which application.
So what is best for 4 Ch planes, or Best for Quadcopter/Race drones... etc.....

Would love to know what is best for my application. 4Ch plane.

Its not the application but if you have a flight controller or not. Use PWM for a plane w/o a flight controller. If you have a FC, use what ever it can use.

Most servos need PWM, don’t care if the PWM comes from a Rx or FC. It’s easier to connect the Rx to the FC with something other than PWM
