I don't know that you can make those broad claims about revolvers, or any gun in general...
ACCURACY
My model 442 is a very accurate gun with handloads. Most people, however, cannot shoot it well without extensive practice. Neither design is more inherently accurate. Revolvers don't deform bullets, but can get out of time. Autos don't get out of time, but can be poorly fitted.
Advantage: Neither
RELIABILITY
I have several autos that have been quite reliable. I have had some that weren't. I owned a Taurus revolver that would not shoot a full cylinder. Revovlers do have the advantage though in that even an auto has been 100% flawless, you cannot shoot very reduced loads through it. Sure, you might be able to load a few hundred FPS slower, but think about the difference in fps in a .38 SPL to .357 Mag revolver.
Advantage: Revolver
ERGONOMICSI like the fact that you can put any kind of grips on a revolver to fit your hands. I also happen to think that the Colt SAA "plow handle" design is the most awkward, un-natural design that anyone could possibly come up with. Many larger revolvers are also very muzzle-heavy. Advantage: Neither
SAFETY Maybe DAO revolvers have a better track record, but I'd be willing to bet just as many people had negligent discharges from loading 6 rounds under a single-action revolver without a transfer-bar or hammer block safety as have Glock owners.
Advantage: Neither
POWER
Maybe. Depends on if you're going by virtue of the cartridge, or the combined effectiveness of the cartridge and how many rounds it holds. .460 S&W is pretty formiddable, but with a gun that large and heavy you might as well have a rifle. For guns that can actually be carried practically, the advantages are about equal between autos and revolvers. Advantage: Neither
RUGGEDNESS is hard to call. Revolvers tolerate neglect better while Autos are more resistant to abuse.
Advantage: Auto
SIMPLICITY
Autos: Insert loaded mag, rack slide, fire, and gun ejects cases. Pretty much the same across the board. Only consideration is the addition of a manual safety.
Revolvers: Method of inserting cartridges may involve opening a cylinder, rotating a cylinder, "breaking" the gun open, or completely removing and reinserting the cylinder. Ejection may be automatic, or it may require the use of an ejector rod. The ejector rod might have to be pressed once, or many times. The ejector rod might not even be an integral part of the firearm.
Advantage: Neither
I think many people are quick to say that revolvers have all of the above advantages. Closer examination, however, reveals that in most cases, advantages are the result of the design of a particular firearm, and not simply whether it is a revolver or semiauto. The main advantage of a revolver to me is that I don't have to look for my brass, and I can load as light as I want to. Neither of those is really an advantage if you ever had to defend yourself with a handgun though.
What it all comes down to is how well suited the design and construction of the particular firearm are to the intended purpose of the gun.
