There's a LOT of specs to consider, but when it comes down to it, I would choose PC.
Why? Because PC always has the latest technology out (processors and graphics) and Mac is usually right behind it. Which means if you're a gamer, you want a PC. It'll run a lot smoother and quicker. Macs will have more of the lower graphics and more lag. Youtube videos will load faster on PCs and you can watch 720p/1080p videos on PC faster. (This all depends on your processor/graphics of course) but when you compare PC and Mac at its latest technologies out, (every time) the PC will be ahead. That's just fact. That's always how it's been.
Don't get me wrong though, Mac is amazing also. You just need to get used to the Mac setting if you usually use PC (which I'm sure are the majority).
IN MY OPINION, Mac is better in the sense that it has THE BEST keyboard and MOUSE PAD! (I LOVE MAC KEYBOARD). It's just so nice to type on. It also has nice Microsoft Word viewing. If you're an art-sy type of guy, Mac is the laptop/computer for you because it's more easier and usually the programs, like photoshop, garageband, MUSIC stuff (like fruity loops, logic pro, etc) will just be more easily accessible. So artists of all types (painters, musicians, performers) you probably would like Mac better.
So overall, EDITING wise, Mac wins.
But, PERFORMANCE wise, PC wins.
My brother has a Macbook Pro and I have a HP Envy 14 (PC), so I kinda have access to both.
Obviously, if you're going to get Mac, you don't need to research cause MacBook Pro is the best laptop they offer, but if you want a PC, research on the processors (Intel Core i3, i5, i7) and graphics (GeForce, ATI Radeon, etc.) I would say the best brand for PCs have GOT to be HP and Samsung HANDS DOWN! But go for the HP Pavilions and up; they usually are the most reliable.
Hope this helped. If you guys have questions, let me know.
