Nice to hear you've got Revit running well via Parallels. I've seen many others do the same with Intel-based Mac Book Pros and wouldn't deny that Apple make good quality hardware. I've owned many Apple computers and other products over the years and learned to program on an Apple IIe, so I don't dislike their products in general.
Intel-based Macs might not be quite as fast running Revit as a PC, but they're still a valid choice if you're looking for reliable, long-lasting hardware and/or want MacOS for other purposes. I personally now prefer PCs overall because I find the MacOS interface make it difficult to be productive (and have always found Unix based OSs rather tedious) and have found that Windows gives far greater options for software, hardware and 3D graphics, and if you are prepared to spend the money (laptops) or spend time building the right rig (desktops) you can have something even more reliable and durable than a Mac. That's just me and I can fully understand why people used to go with Intel-based Macs for Revit, although I must say that it's usually been either the more tech-savy or at least Apple commited who've been successful and the novices often stuggle with the many complications getting Windows to run on MacOS (I spend ten times as long sorting out problems with my students runnign Revit on Macs as on Windows, and only a small fraction use Macs).
My comments have mostly been in relation to the apprioiateness of the M1 architecture (and to a lesser extent the MacOS) for software like Revit, which is obviously a 3D graphical program and also doesn't run natively on MacOS. Intel-based Macs to me were just well-built PCs forced to run the MacOS. The new M1 Macs are a different story, and it really is experimental territory trying to get Revit or any 3D graphical progam to work with this new architecture. The very nature of ARM and SoC would seem to preclude high performance 3D graphics, but you never know with their next generation of processors Apple might pull another rabbit out of their hat (because the M1 is pretty impressive in most respects except 3D preformance) and come up with a way of making this architecture competetive with x86 architecture with dedicated gaphics. If Apple's new processor architecture (along with Metal on MacOS) does become competitive with x86 Windows in the 3D graphics workspace, that might give Autodesk some incentive to bring out versions of their software for ARM, but until that happens, PCs remain the recommended option for Revit
