I am in a similar but more difficult situation.
My music oriented business has been primarily Mac, with only few Wintel machines running custom accounting software. We currently are planning to move to a new and bigger premise, with a proper dubbing stage, increasing staff count in an open office area, and expand into video/photography as a media outlet. If the expansion happened in 2008 then the decision would be clear - just switch everything to Macs. The sheer ease in dealing with mountains of interfaces and various media alone was worth it. But now it is a tough call. CoreAudio is still there (despite its stability lately), but the power for DAW is too expensive to get. Video centric workflow is dandy with FCPX, but it is a limiting option in both workflow if not hardware performance. Even general day to day tasks on macOS isn't as responsive and rock solid as the Snow Leopard days, the GUI lag is noticeable even for the reception lady.
What Macs still somewhat excel is the rather painless plug&play nature, driver related issues are there but a hell lot less than on Windows. But if the Touch Bar MBP with just USB-C, and iPhone 7 axing 3.5mm, or all new Macs losing aux-in & TOSLINK are any indication, it seems Apple isn't so determined to offer this painlessness if it benefits them to lock users in, or just plain bean-counting. I still find it unbelievably difficult to get my iPad Pro to collaborate with my Macs where the best method is still AirDropping files back and forth...
We don't use Windows 10 heavily but I have to occasionally do things in it, have to say it has gotten much better since Vista days, but still lacks a certain degree of coherence and comfort. I don't know which is harder, hoping Apple to pull out of its rear, or waiting Windows to suck less. Even with machine cost out of the question, the sheer uncertainty concerning Apple's commitment to the platform is troubling enough.
