First off, you can't really equate the total mass of the shot with a single projectile of the same mass. The ballistics and terminal effects are not the same.
A lot of people think of shotguns and shot in general as requiring less aim due to spread. I would suggest exactly the opposite, the spread requires you to make a very precise, center hit in order to keep as much of the payload as possible on-target.
In terms of efficacy, I will defer to my standard position--getting shot sucks. With regards to intimidation factor (a valid concern), I hold that a predator isn't concerned with what the prey is equipped with. What he is concerned about is the willingness and preparedness to use that equipment.
The one example of a Governor I've seen in action wasn't a very good example of a Smith and Wesson at all, but that's all I've seen--one example.
I would feel much more comfortable with a conventional pistol cartridge. .38 Spl, .357, .45 ACP--anything in that range. .45 Colt is an overlooked cartridge, but the size makes it difficult for most people to conceal compared to other options.
