Bizarre to imagine the development gap in-between 2013 to 2019 for the pro users... Unacceptable.
Well, there is the stop-gap iMac Pro, but it comes with a glossy display many pro people don't like or need.
But otherwise, that's what you get when you rely on a company that clearly wanted to quietly slip out of the pro market, discontinued the X-Serve, neutered OS X server to the point of being an app addon, the TrashCan Mac Pro was not really Pro, MacBook Pro Touchbar wasn't so Pro with the USB-C only interfaces, etc, etc, etc...
With PC's, you have many high end workstation manufacturers and HIGHLY customizable compared to what even the Tower Mac Pro's used to be, or you can build one yourself with high end off the shelf components.
I work in the printing/publishing industry, which was heavily reliant on Macs, due to their superior graphical environment and reliability.
Almost all of our clients have switched to PC's because they're cheaper to buy, cheaper to fix, upgradeable, and cheaper to eventually replace.
We used to have dozens of Macs, now there is a handful left to support some legacy customers. It's all PC now, and it works well.
