PC has more variety in software (especially indy stuff), and I can afford a more powerful one for the same amount of money, which helps for both work (e.g. neural network simulations take a long time) and fun (3d graphics rendering), so i can't ever see myself spending money on a Mac due to more cost for worse hardware.
I guess Macs are safer for web browsing since they're not targeted for viruses and such as often, but I know enough about computer nerd stuff to never get any malware, and have things set up so even if I get some I can kill the system drive without losing anything else, so I can, in theory, get rid of it quickly. I need to get the rest of my family switched over to Macs though, I'm getting tired of the endless task of cleaning out their PCs every single time I visit.
