I was once a MAC guy, for many years, actually, but then, after a decade in academia, I naturally switched over to PC systems which supported and interfaced with all of the software I was using for my job. That stuck, and I have found that I prefer PC formats much better for my needs, professional and personal.
Windows user all the way. I'm a stickler for old habits, and I don't intend to swap to something new, unless it's so good that the world decides to move on to the new thing. But since OS is about as popular as Windows, I'm staying with what I love.
Also, Windows computers are cheaper and much better for gaming, so I see no reason to try out OS.
I utilize Ubuntu because it's a lot more adaptable in regards to setup than Windows as well as Mac, and has no infections to bother with. This flexibility, nonetheless, does mean that you can face issues with your setups rather quickly, but once you get the hang of it, it does not actually occur that typically.
I am fan of fedora OS but now a days I use windows and Ubuntu. Windows, because it has the best GUI among all the operating systems I have seen so far.
Ubuntu because of its simplicity and most people use it. We must understand that operating system is for doing your tasks. So, you should choose one which helps you satisfy all your needs.
In the past I didn’t have a very powerful system and that time I used Ubuntu as my host OS and it was working very well. I used Fedora too for quite some time and I liked fedora over Ubuntu as it was more stable with my system and I knew how to use it very well. I generally used to mess up my Ubuntu earlier than fedora.
However, I find windows to be best for a normal user who needs tools to satisfy their work and you can later prioritize your tasks and see which one will serve you best based on the configurations of your computer.
