Apple vs. __

Apple vs Android: Apple. Why? Because Apple has clean, simple operating systme. Apple phones have premium feel.

Mac vs Windows vs Linux: Mac. Why? Because Mac os x again is very clean operating system. It looks really nice.

My 2nd choice would be Windows because in Windows you're able to do GPU heavy thing and/or gaming which you can't do on Mac Os x.

Linux is not so good for everyday use because it is really complicated at first time user and many applications are not ported to Linux. But Linux is free. Linux is good for servers/quantum computing et cetera, also Linux does not have viruses as much as Windows does.
