I will say that if your choices have been narrowed down to the 4 shotguns listed in the above poll, you have done a lot of homework, spoke with a lot of people, read a lot of info, maybe watched a lot of videos also. The reason I say that is because not one of those shotguns are garbage or junk and each and every one of them would serve its purpose (well and beyond) just home defense.
If I had to pick from those 4........ (if I felt the need to spend that kind of money on a home defense shotgun) I would choose the Beretta or the FN. But then again, If I was slinging that kind of money, I might just save a little more an get a Benelli M2.
I Have eyeballed shotguns in the price range of $1000 and up before, but it wasn't for home defense, it was when I was considering getting into 3 gun.
I would agree with what all the others have said about buying simple for home defense. You don't need extravagant for home defense. In fact, I even suggested in another one of your posts that you could purchase a simple bare bones model 1100 and do some add-ons yourself and save yourself cash for a case of ammo besides.
If you build it yourself, you are only limited by your imagination and what you actually would need. (maybe a mag tube extension) An old beat up Remington model 1100 with a +2/+3 magazine extension will do (everything, exactly the same) as that 1100 tactical will do in a home defense situation. $270 -$350 (for used 1100)... $70 (for extended mag tube & spring)....... I can have a Remington 1100 that goes bang every time I pull the trigger without having to reload for 7-8 rounds for anywhere between $340-$420.
It has become apparent that you have your mind set on the 4 shotguns listed in the poll, and there is absolutely nothing wrong with that. I, along with the other members here are just suggesting you don't have to fork over that kind of cash or purchase something as extravagantly set up (or marketed for certain customers) depends on how you look at it, I guess.
If your heart is set on those final 4, my last suggestion is this, get out to your local gun stores that have those shotguns on their racks. Handle each and every one of them, shoulder each one of them, work the action on each one of them, inspect the ergonomics of each one of them, find which one feels best in your hand, find the one that naturally engages to your shoulder and allows your master's eye to acquire target area the quickest and most naturally.
In the end, it will only be YOU who can decide which shotgun you go home with.
