Okay since this is the comment section I will summarise as much as possible. If you are the type that likes to game on computers eg on Steam, Windows is your definite go to. If you use any programs on your windows frequently double check they are supported on Macs. If they are and you are not that much of a gamer and you have the money; I would go for a Mac. They are expensive but have many perks. Strong and last a very long time if taken care of, hold their value, sleek, very very rarely lag and have a pleasing GUI (only once you get used to it). Windows lose value quickly, can start lagging quickly unless has amazing specs, in most cases don't last very long, weigh quite a bit BUT windows supports everything Macs support and much more. Finding stuff you need online is so much easier for Windows so it really depends what you need. Worst comes to worst you can get windows downloaded for your new Mac.
