I'm not about to dispute that, but in over twelve years using a Mac in a live music environment, I've not been let down once. With windows, I've had multiple failures, both on the software and hardware, so I will stick with what's working for me.
As pointed out above, I do still use both platforms regularly, but I use Windows on a Mac, where ironically, it runs well, I've not actually had an issue on any of them (I have three Macs with Windows partitions).
To be honest, disregarding all of the above, I'd still buy a Mac now because I like the fit and finish, the ergonomics and the look and layout of the OS and the effortless integration with other Apple devices... I'm far from an IT guru, so anything that takes effort to set up will annoy me, I want it to work out of the box and Apple stuff does that, albeit with a price premium.
I am disappointed that they've deleted the Touch Bar on new MacBook Pro models, I've gotten quite used to that and it's a useful tool with a lot of DJ software, it'll feel like a kick in the teeth losing it when I come to replace my existing MacBook.
