I personally use a Mac and I love them, but I know individual people will have their individual preferences. However, I can say that for creative endeavors, my experience with Macs has been superior. Usually even now when I use my Windows machine, I still have to set aside far more time and expect far more stress than with my Mac in accomplishing tasks that I feel should be simple.
The largest obstacle with Macs is that they tend to be more expensive and they're not always as good for certain things like graphic-intensive games, but if you're going to get a work computer, I don't think that's going to necessarily be a major consideration. That said, I still do just fine with my system.
If you're used to Windows systems, though, they've improved significantly over the past decade alone, although there are still some major issues like Win10's occasional "I'm going to lose your user profile which makes your files inaccessible" issue.
Whatever you choose, I recommend frequent saves and archive backup. If you get a Mac, use Time Machine regularly. Either way, be sure to get an optical drive and write to DVD regularly. I also tend to pick up flash drives whenever I see one on sale so I can just backup data on the fly. Just in case! And if there's an especially great deal on an external hard drive, I pretty much always take it. Backups are the most important thing in creative work, because this isn't something you can maybe find elsewhere and download later. It's something you created and will have to create again if it's lost!
I have had exactly one big crisis with my years of using Macs, and almost all of the data -- and all of the creative, irreplaceable data -- was recovered by the Apple Store people. I can't say the same for my years of using Windows, which was a longer time, but also more dotted with problems. I tend to have a more stressful time with Windows, and things that are easy and quick with a Mac aren't always the same on Windows.
Some people absolutely hate using OS X, but it didn't take me long to adjust. I'd recommend, if you can, playing on a friend's or going to a store and trying one out and seeing if you are comfortable with the differences. Macs and their accessories are pretty much always more expensive, but in my experience they also tend to be less problematic. Your mileage may vary!
