Mac. I use a MacBook Pro from 2013, 2019, and I use an iMac for audio and video editing, and I use an iPad for drawing and other design type things. It’s the least terrible OS - with the best hardware - and it makes me feel happy knowing I have the best.
Even if I preferred Windows, I’d still use a Mac part of the time - because you have to test for user gestures that most PCs just don’t have. Also the battery life is much better. And if I ran Linux, I’d still use a Mac too, because it’s just nicer to touch - and that’s what I do: type and look at a screen.
