There are actually several that are good. The way to judge is based on three factors.
1) Potency of the spray
2) How long it will spray
3) How far it will spray
There are some that will go 30 feet and over 10 seconds. Many of the top brands look like a toss up between them when I look. I have only bought one canister so far but you need to consider using it more than once as part of the buying factor because a black bear interested in you is notorious for coming back after the first spray according to some of the bear books I have read by James Gary Shelton. He also recommends BOTH spray and gun and not count on only one method of defense.
I am likewise going to get a .44 magnum in Ruger Super Redhawk 7.5 inch because its increased weight helps with recoil. I shoot one handed and want to be able to use the high powered loads. I shot a .454 one handed and it wasn't fun, but manageable. Some of the .44 magnum loads especially from Buffalo Bore get right up there at nearly the .454 range. Certainly not a 30-06 but we have many cases of successful bear defense with such a weapon. If a rifle isn't legal or practical, why not have a good side arm? Isn't it better than nothing at all? Just makes sense to me.
