If you look at mac hardware they are one or two generations behind windows as far as hardware go. Plus you pay a lot for older hardware on Apple. The reason is comparability and it insure you will be trouble free when working with your project for years to come. I have seen Apple computer running for 10 years with no reinstall of the OS. While windows has been reinstall about every 3 years but this is base on older OS of Windows.
I own an apple mac book pro and it works great for what I needed it for but my main pc is still under Windows. This is due to the fact that all my audio tools, video editing tools and games are more compatible with Windows than IOS. Options are limited to me on Mac but some of their tools are amazing.
Mac runs pretty smooth for being on an old hardware and hdd non ssd. While I feel windows run better on ssd than hdd.
Honestly it will come down to what you need it for. I would personally stick to windows but mac has it places to be in too. Both great units, great hardware and great all around. It will come to personal preference.
