It's like asking, which is the best wife? Lots of choices here, and the Archives are packed with facts, opinions, ideas and wild eyed illusions. Some research there can give you lots of input.
Well, all of the ones you mentioned are good guns. All will work, so the first big hurdle you have already cleared. The rest is gravy.
Decide first if you want semi-auto or pump. I personally lean towards pump shotguns, simply because they are more reliable than semis, all things being equal. But thats me- lots of tactical people use semis, and they seem to work for them.
Once you get the semi/pump question out of the way, you can start narrowing the field. And like Dave said, so a search. This has been hashed/rehashed/rerehashed already
We've rehashed this topic many, many times. I suggest working on the archieves via the search function. This button is in the upper right quadrant of your screen.
Take an evening and catch up on your reading. If you have any questions left over, feel free to post!
