The "bottom line" conclusion of the first link that you posted - Box of Truth "Educational Zone #143 - What Is the Best Weapon for Home Defense? - A Serious Discussion", is Rifles > Shotguns > Pistols.
The next four links that you posted are just penetration tests of walls - which is only one component in the overall decision making process for what someone would use for their primary HD weapon. So IMO the second set of 4 links does not "back up" the conclusions put forth in the first link.
