I use Macs in preference to PCs, with the exception of the PC that runs Sonar.
Macs aren't perfect and they have their own issues from time to time. OS X is completely different to Windows, which is one reason I prefer Macs (I like Unix). To say OS X is "simpler" than Windows isn't correct, it's "different" to Windows. There are semblances to iOS in look and feel and OS X and iOS devices integrate pretty well generally speaking.
From a DAW point of view it has to be said Core Audio/MIDI does make things much simpler to set up, and no need to dig around in the depths of the system switching core parking and wifi off. Built-in wireless MIDI networking is nice.
Retina screens are considerably better than HD 1900x1080 monitors.
Macs don't blue-screen crash like Windows, but they can and will lock up requiring a forced reboot sometimes. Like with Windows that problem's often down to a third-party driver or hardware.
But they cost quite a lot more than an equally powerful but maybe not so well engineered PC (those alloy MacBook bodies are expensive) and in the PC laptop world if you spend Mac levels of money you will get something more powerful. And there's no way to expand a Mac other than via Thunderbolt. Which works well but anything with "Thunderbolt" on it tends to be expensive, and many external drives and enclosures that claim to be USB3/Thunderbolt are really USB3 ones internally with a Thunderbolt socket added. The catch being that while Thunderbolt supports the SSD TRIM command USB doesn't. You also have to switch TRIM for non-Apple drives on using a terminal command.
I have Logic Pro X on a 2015 15" i7 MacBook Pro. I could live with using it as the only DAW, but the plugins it comes with are generally weaker than those you get with Sonar Platinum (with the exception perhaps of Alchemy). I personally could use Sonar Platinum with no third-party plugs at all if I needed to, but not Logic.
Sonar on OS X? It's been asked for from time to time, but the systems are very different and I would imagine it would be a huge task. There's also the pricing to consider. Logic Pro X is inexpensive as full-blown DAWs go, and can handle Garageband files and projects. Every Mac comes with Garageband. And Apple make their money mostly from selling hardware, not software...
