First, did you not read the part where the 2018 XPS 13 was given 4 1/2 stars and an Editor's Choice Award, while the 2018 13 inch MBP was only given 3 1/2 stars and no award? That was based on a "whole laptop" analysis, which this site failed to mention.
Second, some large organizations do buy computers and add upgraded components or contract the upgrade of those components out. The organization I just retired from did that all the time. They also wiped all of the laptops they received, then used the exact same ghost image of Windows -- regardless of what version of Windows the laptop original came with. They did the same with some Apple devices. They contracted out iPhones, then bought cases that added extra protection to the iPhone while changing the lightning ports to micro-USB.
Third, no one takes the manufacturer's word on exactly how fast a SSD is. Most tech sites (like Tom's Hardware) will benchmarks the read and write speeds for SSD and share the averages with the public.

You keep mentioning the SSD controller chip and that it is "built into the laptop." This is confusing me because, from my understand, the controller chip is normally built into the SSD itself.

Motherboards in Windows computers have a connector that the SSD is attached to, and this interfaces with the rest of the system through a standard such as SATA or PCIe. As long as the interfaces in each Windows laptop follow the same standard, SSD performance should be the same in those laptops.
Yes, some Windows laptops have multiple M.2 slots and a mix of M.2 slots and SATA slots. Yes, you should be able to set them in RAID 0.

I don't have the time to go "profession by profession", do you? Plus, I'm afraid that if I do, I will probably miss someone, so in this instance a little "hyperbole" is warranted in order to save time. A quicker way to conduct this analysis without polling ever single professional is to look at total operating system usage across enterprise end-point devices. Of course, an (safe) assumption will need to be made that each business is using the operating system it needs. Here is a breakdown of this information worldwide from 2017:

As you can see Windows is being used in almost 3 times as many professional settings as MacOS, and twice as many as both MacOS and iOS combined. BTW, the iOS devices listed should account for the iPad's various uses as well as iPhones used as point-of-sales devices.
