The shotgun is intimidating. Does that mean you are outside of cover or concealment and pointing the gun at the opponent, so the opponent can see you and talking?
While talking like that - you can be shot. When someone is posturing and flapping their lips - the opponent can draw and shoot you. If they have the gun already out, easier to shoot said blabbermouth. Seen it done and done it in FOF. "Drop the gun, get off him" - oh, dear - I think I will shoot you in your monologue and I did. "Put you hands up and drop the gun" - well, I did and then - surprise - when the opponent relaxed, I reached behind my back for an airsoft BUG and shot him in the noggin (we were masked up). Oops!
I said this before, so much internet expertise on kinetic energy and stopping power - people love this. I said, take classes or shoot matches with each HD gun and see how they actual work for you in extremis. Otherwise, the discussion is just hot air.
Did a run once in a 360 degree shoot house, with a double barreled, multiple opponents (dummies and some that could move and surprise you). We simulated being in sleep dress (use your fantasy imagination - simulated with a long t-shirt over your clothes). You had the gun and a box of shells. Now go move through it. You had to move.
Oh, here are two opponents - one shot each. Surprise - out pops a third. No time to reload - so I had to close and butt stroke him with the shotgun.
Now we also had hearing protection on.
My point is that folks are way to glib in choosing HD guns without a bit of experiential testing. Racking, intimidating, can't miss, knock you down - those are just cliches. If I had to use my 8 shot 1300, I'm capable. I would be fine with. I just think one must exam the choices in depth. Eight is enough until it isn't but can you handle the gun well in the HD situation?
