I personally sort of disagree and agree with you
If I was
primarily running windows based Autodesk apps I would 100% be buying a PC. They run quite badly on a Mac in comparison even in bootcamp. If say 20 - 30% of the time, then a Mac is a good buy. Really it depends on amount of use within bootcamp. I am not experienced with solid works but could imagine a similar experience to Revit.
Revit is no way as smooth as it should be, which I put down to the video cards in Macs, not being Nvidia. I am not saying its not ok, but certainly not as fluid experience as it could be.
I use Fusion 360 and Autocad within MacOS on a maxed out 2017 iMac and Revit in Bootcamp. It is a far better experience within MacOS. Have lived the MBP experience and not again thanks [fans, speed etc]
I am expecting to be using Revit more shortly and if that is the case, will get a PC for that [probably Dell XPS 15" or similar]. No more fans blasting, and as noted above bad battery life [as the video card is on permanently].
So as said above, yes depends on applications as much as anything. Autocad + fusion 360 are fine, Revit not so much, and can't comment on Solidworks.
Just buy one [maxed out], stick bootcamp on it [download windows from MS site] and see how it goes. I did this, and it was pretty clear I needed something more than the current machines, but for you it may work fine.
