@ghostwind - As a Window and Mac user who still loves the cleaner Mac interface and appreciate the full Mac OS eco-system (phones, tablets, laptops, HomePods, appleTVs), I can tell you that Windows 10 is night and day from what you know of and experienced.
I have an Asus ROG gaming PC and a Dell XPS 13 and have no issues switching back and forth. I've never experienced a kernel panic or even a restart from it. Unlike back in the way where it could be a frustrating experience in occasional BSODs.
If you are in the Adobe CC camp, the way Apple is accelerating the development of their own apps towards AS optimization, and the way Adobe is lagging behind in every aspect - GPU optimization and multi-CPU optimization - Windows 10 is the way to go.
Unless you're looking to move into FCP and/or Resolve, I would look at Windows. And if you're not a build-it-yourself kinda person, have you seen those Lenovo ThinkStation P Series with RTX cards? Holy cow.
As for myself, I got the Mac Pro patronizing the ecosystem and loving the industrial design still. Also knowing I can boot into Windows every now and then if needed (which I assume you cannot do with an AS without third-party virtualization in the future.) I love the upgrade ability and crossing my fingers Apple pulls through with more MPX modules alongside the existing AS transition.
When the Mac Pro AS version comes out, I'd like to buy it as well but with the condition that there is internal third-party expandability.
I have not looked at the Leonovos, I will check them out. I believe you that Windows 10 is a lot better, but I feel like I need to spend 1-2 months researching PCs, chips, builds, etc. before I can understand the "scene". And then in 3-5 years, if I go back to a new Mac? Another painful transition. Hmm...
