I'm in the same boat, just more from a Photography standpoint.
Oldest Mac I own is a 2012 MBP and I really do not see any appeal in any of the newer machines. I built myself fairly high end Mini ITX Windows machine for a fraction of what a comparable Mac would cost. Only downside is having a somewhat bigger PC on my desk.
For video editing I was very surprised at how quickly I picked up / understood the Free version of Davinci Resolve after looking for a Final Cut replacement for my gaming PC.
