Windows is not that easy to learn. Just because people are used to it (from school or work) doesn’t mean it’s easy for new users. I’d argue neither is macOS, but the closer Apple made the UI to be similar to iOS, the easier imo it would be since many more people nowadays get familiar with mobile first. Unfortunately for Microsoft, the lost the mobile OS war.
They both have a dock/taskbar with quick links to apps and currently used apps (I prefer to have the windows each have their own spot, personally), a launcher, a desktop space, a file browser, etc... They're far more similar than they are different. They both have some quirks that are not intuitive at all but I don't think anyone struggles to use either.
As for powerful, it’s undeniable. The base M1 Mac can already go head to head or faster than a core i7, a high end CPU. Most PCs out there are the i3 or i5. Whether you need the power or not is a different story, but imagine a base config iMac computer that can handle hevc 10 bit videos with ease, while even the best intel PCs are choking. For amateur video editors, Apple silicon is a huge deal.
Who's going to notice this, especially at the new users they're targeting? Remember when Apple would go on about how specs are trivial and the experience is what matters? Nobody's going to notice their Office documents or web browsers working any faster, media playback, etc... benchmarks and video rendering time don't really matter to most people. It isn't a bad thing, but the marketing term "astoundingly powerful" is rather meaningless.
Comes with apps, yes, this is mac’s strength. There’s Preview, which is a powerful PDF editor. To edit PDF on Windows, you have to either buy Adobe Acrobat (not the free version) or find another 3rd party app. And there’s no parity of macOS Photo and iMovie on Windows in terms of software quality with the ones that come with Windows. Also, with many Windows machines, HEIC support is not included, you have to buy it from the Windows store. (There’s workarounds, but normal people wouldn’t know)
You can mark up PDFs right in Edge browser, including with pen/highlighter. Photos is definitely on its own, but iMovie doesn't come preinstalled anymore, nor does Garageband. They're okay at best (check out their reviews on the app store currently) and you can just install DaVinci Resolve for free on whichever platform anyways.

You certainly have far more choices for software with Windows, free, paid, new, old -- it isn't even a contest. Almost no software is made only for Mac that isn't made by Apple, namely Logic, FCP, and Xcode (for which you need a Mac, but is that a good thing?)
Much all of the software we use at my university, especially in engineering and science, is only supported on Windows or in some cases Linux as well (granted, some of it is old and/or pretty awful). ie. Intel Quartus / Xilinx Vivado (engineering), SAS (for statistics), ANSYS (physics/engineering), Altium, OrCAD, etc... and of course games!
MacOS major weakness is not the free software updates, but the software support longevity. This is the big advantage of Windows. Eg. I have a 2012 Mac mini. It’s already dropped by Apple with Big Sur. Meanwhile, Windows 10 can still run fine on way older computers and intel Macs. In fact, many old intel Macs’ lives can be extended with Windows (the irony

).
It's actually quite a shame since the Mac hardware seems to age like wine. I'm always amazed at how well even 10 year old MacBooks have held up, so it saddens me when software support is fully cut. It sure is nice that Intel Macs ' life can be extended with Windows (and Linux!), but I'm not sure what will happen with the M1 Macs. I hope that given how powerful they are, they will be supported longer.
I do like being able to use older software, sometimes because it was expensive and still does the job (Photoshop CS3), sometimes for nostalgia, and of course older games. I'm always amazed that such old software can still run without much trouble.
Anyways, all this is to say that I'd like to see Apple focus on substance rather than what seems like low-effort and non-unique marketing points.
