Each type of weapon used has it's limitations. Does it take a better hunter to get "bow close" rather than drop a deer at 100 yards or more with a gun? To a degree, yes IMO.
I have also seen guys get deer that had no experience and just lucked into too though.
I agree that far too many hunters, regardless of weapon choices, wait too long to practice...or scout...or get ready. Around here, the guns go nuts in the days before the opener. Some even at night...
Personally I have always tried my best to be ready. I have passed on gimme shots because I didn't feel I practiced enough, due to various reasons.
It is a personal choice. And I agree that we owe our best efforts to the animals we hunt.
