Honestly, I'd need to put more rounds down range and try to be a bit more "qualitative" with my analysis before I could give a personal opinion on that. There's obviously the shootablilty aspect, the carry aspect (ounces==pounds, pounds==pain,) and the impact performance aspect, that all have to be factored in to the equation.
One thing I've learned from both personal and others experience, you want your support hand (the one through the loop) to be basically locked straight out. I find it works better if I make it handle the bulk of the recoil, and let my strong hand do the fine tuning of my aim.
I have let to have either recoil enough to where I worry about my pretty face, but I have had the safety lever bite into my hand and draw a good amount of blood. Don't let the strong hand slip!
In a house, a handgun is more dynamic, faster, and easier to operate one-handed if necessary.
And I can be much more precise in aiming against a bear with a good handgun.
Buckshot has its own limitations there. One is speed, one is accuracy.
The Shockwave's more toy than defensive shield, as a practical matter.
