hunt with a Chessie who will sit on a whistle. You'll get far more pheasants than hunting over any pointing breed. Especially in the Dakota's and Montana. Sharptail....get a pointer
Depends on how, and where you hunt. In milo, cut corn, and cattails, your right. But push birds into the coulees and natural prairie landscape where birds spread out and can be pinned, and a pointing dog will smoke a flusher/retriever. You throw some snow on that milo, and that changes everything as well.
The grassland where we hunted was mostly about 3-6' tall. Plowed fields and cut wheat were the only open range. Hard to see a dog on point looking out over a couple thousand acres of chest high grassland. That's where the chickens feel safe.
thats why we have garmin tracking collars. you don't need to see your pointy dog to know where he is and what he is doing.
And beepers with point mode.
Ahhh nothing like the sound of a truck backing up for ambiance while your out hunting... or even worse, that fake hawk scream... or bobwhite chirp. I wish they would make those things illegal.
Doesn't bother me a bit, turn off my hearing aids and it's back to peace and quiet. 
that kinda defeats the purpose of having a beeper doesn't it?

different strokes for different folks.
I value stealth for my hunting trips. any human/unnatural noise tips the birds off and puts them on alert. I can stand beepers and people that constantly hack and call for their dogs out side of a field trial.
to me a good day in the field is when I only have to say "good dog" and "load up" it doesn't happen as much as I would like, but I really enjoy running silent when I can, and I feel I bag more grouse because of. too often have I heard birds that were pinned down flush at the sound of a beeper.
I do really like the tritronics beeper that can be activated with your transmitter, that is very handy and a safety feature to boot. kinda like when you loose your car in a huge parking area and push the lock button on your key fob.
