Comments like these are hilarious. Making ridiculous comments like "Macs Increase Productivity compared to PC" couldn't be anymore flawed. It's all about Hardware. Hardware will depend more on how fast, and capable your machine is.
Software optimization would play a role on how well the software runs, but not necessarily how well it performs. Anyway, this video shows how cheaper Windows PC's will outperform Macs with Productivity.
Two can play that game.
It boils down to how well your hardware and software play with each other. Adobe premiere runs better on PCs because Macs don’t use nvidia graphics (which Apple is working on remedying with metal).
There will be some scenarios where PCs will prove the better choice, just as there will be scenarios where a Mac is the better alternative for the user. Just ask all the youtubers who swear by FCP because adobe is such a resource hog.
