I used PC's for years even built a few. They worked very well. But Mac was the first time I didn't have to do component/driver research and tweaking to get the performance & stability I needed at low latencies for virtual instruments. Everyone's mileage will vary of course.
I'm not expecting a Mac version of SONAR, but there's a certain nostalgia about debating the merits of such, -daily- over a decade ago. 😎
