It's just a matter of your personal preference. I personally hate having all the frequencies split up. I like hearing all the different positions, so it's best for my preferences to have all the frequencies on a single feed. Sure, you don't hear every word that is said, but why would I need to do that?
It's possible to listen to multiple streams at once to get the same effect, but then when there is audio on both streams at the same time, they step on each other and you just hear a mish-mash of communications.
To each his own, I guess.
