No offense
@TheJokerz, but having seen a Mac back in the 90's hardly makes for a qualified base comparison.
It's also funny to read MacOS is "badly designed" – MacOS has had design guidelines for ages, which means you feel right at home in whatever program you use. Not like Windows, where everybody reinvents the wheel up to and including the UI. Not even MS themselves have a friggin clue. Take one look at the Settings, there's a modern version and an old version. Some things can be done in the new version, some only in the old one. Very straightforward. Not.
Fact of the matter is, people get used to logical bloopers like clicking on "Start" in order to shut a machine down or being asked if they really want to do something after every single click. And change usually sucks until you get the hang of it. But that's not the system's fault.
I'm running 7 Windows machines and 2 Macs in my office and the only ones that just work 24/7 are the Macs. Apple has gone to great lengths to ruin MacOS during the last years, but it's a certified UNIX after all. Restarts happen app. twice a year, whenever there's a major update. That's it.
TL;DR:
Go MacOS, if you couldn't be bothered to fumble around with your system and you just want to get stuff done, especially on the creative side. It's also a no-brainer in case you already have an iPhone / iPad / AppleTV since the overall integration is just great.
Caveat emptor: IMHO, the current Apple hardware lineup is a disaster. Feeble graphics, old processors, funny design decisions. I certainly wouldn't recommend to jump the gun, at least wait until after WWDC (beginning of June), there are rumors regarding certain updates.
Go Windows, if you like to play modern games or if you require services or software which feel most comfy on that system.
N.B.: There's also the best of both worlds, reserve a 2nd drive / partition for MacOS and dual-boot either one according to your mood. I'm not going into details here, though, since I'm not familiar with the official forum stance regarding that topic.
