Yeah I don't want to get into that debate lol :). I'll just say if you are comfortable with using a 20GA... the 28 will do all that.
If you get a 28, know the ammo is dear and that not all 28 ga shotguns are built on 28 frames. If you get one though... oh the joy!! Light, and light kicking! Yet effective! Can you hear the love in my voice lol?
