I voted Remington (870) even though mine was retired when I stopped trap shooting. A Winchester 1300 "Defender" sits next to the bed here. I haven't seen any opinions on the Winchester 1300 in here but I like it OK. The reason I don't use the Remington for home defense is because it is a high grade trap model. It awaits it's possible use in the future.
Can't say I've shot all of the above, but I have nothing but good to say about my Mossberg 590a1 w/ the Vangcomp modification, surefire light, extended mag & underfolding stock. I've had it for years & love it. Yes, the underfolder is uncomfortable when shooting slugs, but that's OK...I like how compact it is w/ the underfolder.
I don't have any experience with the high dollar trap/hunting shotguns. I have a mossberg mariner w/pistol grip,heat shield and 18' barrel, that I would consider my all around favorite. I also have a Remington tactical express w/ extension tube and AR15 style collapsible stock,my only complaint with this gun is the crappy placement of the slide release. I also have a remington 1187 premiere semi-auto which is a beautiful gun but I have not fired it yet.
