Depends on what you want to do? I'm a graphic designer and if you stuck me on a PC I'd throw it out the window(s) lol so it's Mac for me all the way. But If I was a gamer then I'd pick a PC, but I'd still probably end up thowing the damn ugly thing out the window.
If you use pc then you are going to like pc's, if you use macs you are going to like macs. I have used both mainly for final cut pro and photoshop and I still generally prefer pc's. I will never get over only having a single mouse button.
