Rupes UHS topped with Wolfgang Fuzion

You missing a lots of thing not using UHS, HD speed is fake correction and it does fill swril not correcting it, while UHS is a true 1 step correction compound. You can try using Speed and UHS on some severe paint damange and then wipe out with Eraser or strong IPA, and you will find the fact. Me and my detailer friends use to have lots of customers furious back to our shop within a month when all those defect coming back again after a few wash, and once we use UHS it is zero case complain.

As a result From something that fill-in (I dont say it's a filler but it's something in Speed) and it wax, it's sure that speed will feels smooth at finishing compare to UHS that leave no protection behind. But once you apply some quality after UHS polishing, then it's game over, you will have no follow up return complain.

Clearly Mike is a genuinely nice guy and is always VERY respectful to everyone and willing to take the time to write you an in-depth informative response.
Personally, I would have been more blunt and encouraged you to educated yourself on the difference between a 1-step polishing compound and a cleaner wax (popularly known as an AIO). Then I would've tried to argue that pinnacle souveran paste wax is "fake protection" because it doesn't last as long as opti-coat pro.
See what I did there?

How long does the protection last with HD speed? On a maintained and washed regularly vehicle.

If you just wash with products like D114 or Mckee's N-914 and don't use spray wax/spray sealants/detail spray I would say 4-6 weeks.

Longevity is so subjective, it really depends on so many variables, paint color, garaged or not, environment etc. But that pretty much sums up longevity of any product.
