Default PUMP vs. PROP

OK, big question, all takers.

All of my experiance is in jet boats, I have only stepped aboard a
prop boat a couple of times. So naturally I tend to gravity toward
what I know, and I admit that I am probably a little biased and will
defend my little jet boats with vigor. However, in my continual quest
for more power and more speed I have come across many an individual
that will swear up and down that a jet pump is "limited" and a prop
boat is "limitless".

The main arguments are these:

1. You can only force so much water through a jet pump no matter how
much you build the engine.

2. HP for HP a prop boat will have more responsiveness and overall
speed.

3. Lastly there are no cavetation problems that you have with a pump

Now, I would like to find this all out for myself, BUT, you cant
really go down to your local boat dealer, show you drivers license and
take a couple boats for a spin. At least not at the dealers that I
know of.

Does anyone have some light to shine on this subject? Any
experiances? They would be much appreciated.

Thanks,
