I use both.
I use my Mac for school work, photoshop, music and just general browsing when I'm at Starbucks or going on a two day trip since I think macs are light and durable for that type of thing. (I have a Macbook Pro 13 and I love it)
I use my PC for gaming, cyber forensics, multitasking, video editing and more intensive tasks.
While I love both of them, I prefer my PC due to the wide variety of programs I can use on it compared to my Mac. (It's also 4x as powerful)
