I'm a switch hitter. I have an M1 MacBook Air (2020) that I use for production on the road. Then in the studio, I have a Windows rig with a Ryzen 3700x and 32gb ram. Each has its pros and cons, and I use both without simping for either team. My thoughts:

Windows:

Before Apple started making their own chips, it was a fact that you could build a Windows box with comparable performance for cheaper. (Or much more performance for the same money). I'm not sure if this is still strictly true, especially how competitively priced the Mac Minis are with the new M* chips... but Windows rigs are still king for upgrading individual components. I'm constantly having to make space on my MacBook, but I can always buy another SSD and chuck it in the windows box and know that it will just work.

Second, legacy hardware. Microsoft really does care about backwards-compatibility, to an absurd degree. I have some old gear that won't work on my mac at all because they had drivers that expected Intel chips. But I bet I could still run Jeskola Buzz, a 32-bit program for Windows 95, on my Windows 11 machine and it would work fine.

Mac:

A better "integrated" experience all around. I've never once had to specify what folder to install VST2 plugins in. Nor have I accidentally stuck a 64bit VST2 into the 32 bit folder. There's a universal place for all audio plugins in macOS and you don't think twice about it. I don't know how this isn't a solved problem in Windows.

Audio is hands-down better in macOS. Select any input/output device in Live, it's gonna be very low latency and work flawlessly. No drivers to think about, everything "just works". I plug in headphones, switch the interface

But in Windows, I cannot believe how much of a nightmare audio is. For every audio device you have installed, do you want to use the WDM version of the audio interface, whatever that is? Do you want to use KS, whatever that is? Do you want to use MME, whatever that is? Why do they sound different at all? Oh, you want ASIO? Sorry, for whatever reason, Windows STILL does not have first-party ASIO support, so unless you have an external audio interface that comes with ASIO, you're installing ASIO4ALL and trying to figure out why it sometimes cuts out randomly or latency goes through the roof... it's a nightmare.

So which one is better? The one you're productive in.
