By page 2 this will be "My Snap-On dealer/rep said..." claiming that the Snap-On sockets get an extra coat of chrome or polishing (that and the stamp rolled in makes them cost 4x as much).
Then there will be a link to an old thread with a claim that two completely different 15+ year old wrenches (allegedly) not being made of the same metal is proof that Snap-On and Williams tools are in no way the same.
The internet metallurgists will chime in about the steel used, which might derail into an argument on Chinese steel, but undoubtedly ends with someone claiming they're not the same. But there will be an offer that if you buy and mail a member some Williams and Snap-On sockets for testing, they'd post the results.
And then there's a good chance we'll get the, "Just buy Snap-On for the ease of warranty" (for all those exploding sockets), or "Why not just buy SK/Wright/Proto/Gearwrench/HF/Garage Sale Craftsman instead?"

Personal experience:
Bought Snap-On sockets with my student discount, bought some newer Williams USA to fill in my old pre-Snappy Williams set, saw no difference between the two besides the stamp. Sold the Snappy sockets, replaced with Williams (one set which came with a Snap-On socket on the rail) and filled in the odd gaps that Williams doesn't offer with Snap-On.
Years down the line, still no difference in wear, and can't tell the difference in the sockets besides the stamp.
The "How It's Made Episode" about sockets is filmed in the Snap-On plant, and you can watch Williams get rolled into a socket, so there's that.
