One of the key differences is that compositor is designed to work
properly with live input (such as from udpsrc). If you have multiple
inputs and one of them doesn't produce data (e.g. because of signal loss
or packet loss), it can still continue to output something instead of
waiting forever.

There are many other differences as well, like handling re-negotiation
of inputs better, it can convert and scale inputs on the fly if needed.
