Is OSX a better laptop or desktop os?

So i've been thinking about getting a Mac, but i haven't decided which one to get. I will be getting some money to put towards a computer for college in the coming months, and have been researching both PCs and Macs. My long term plan is to have a pc and a mac, one being a desktop and the other a smaller laptop for portability, to get the best experience from both sides. My question for this post is, is Mac OS best on a desktop or laptop?
