As far as visitors go... that depends. A guy coming up to fish the Kenai or vacation around the road system is much better off with spray. Chances are they'll never even see a bear and the spray is purchased and disposed of locally with zero of the hassles that firearms can entail.
A guy heading out in the backcountry is better off with both a firearm and some spray IMHO- provided they're comfortable with it.
Not to downplay it- but bears are way down the list of things most folks should worry about. Thousands of folks conduct themselves through the backcountry safely with no sign of a bear at all. Camp clean and keep your wits about you and folks are fine. Gotta remember that Treadwell encountered hundreds of bears over years before one finally ate him and he basically did everything you're NOT supposed to do.
Great post hodgeman. Sounds like very good advice.
We see these threads pretty regularly, and I am a little concerned when people new to grizzly country get the advice that spray is useless, and what they really need is a big bore revolver. I still think both can be effective, and the learning curve is easier with spray.
Here is a recent account of spray seemingly helping out, but issues with fumbling with the safety tab and wind issues are both mentioned as well:
