That analogy is garbage because there is no such thing as the best operating system.
The best operating system for YOUR personal needs is different from the best operating system used to control a robot arm.
The end-user (YOU) doesn't "use" an operating system. You use the applications running on top of the operating system. The operating system securely multiplexes the hardware and offers various abstractions that programs use to request the aforementioned resources. You don't manually request the operating system for space in memory. The program does that for you.
I like to ocassionally browse the web with Firefox. I like to program with Visual Studio in C#. I also like to program in C. I like to edit text with vim. I like using grep and awk to search through files while I'm at work.
I use Ubuntu 14.04 with Windows 8.1 running in a virtual machine. I could use Debian as a dom0 under Xen with Windows 8.1 running as a domU. I'd probably get better performance out of the Windows VM but I would also have to go to great lengths in terms of customizing everything.
Seriously. People need to stop asking this question. Most people don't even know what an operating system is. You might as well debate which kernel is better or which shell is better. Why not debate virtualization versus dual booting?
Learn what it is that you're asking before asking.
well here is this analogy from which you can decide...
If Operating Systems Ran The Airlines...
UNIX Airways
Everyone brings one piece of the plane along when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing non-stop about what kind of plane they are supposed to be building.
Air DOS
Everybody pushes the airplane until it glides, then they jump on and let the plane coast until it hits the ground again. Then they push again, jump on again, and so on...
Mac Airlines
All the stewards, captains, baggage handlers, and ticket agents look and act exactly the same. Every time you ask questions about details, you are gently but firmly told that you don't need to know, don't want to know, and everything will be done for you without your ever having to know, so just shut up.
Windows Air
The terminal is pretty and colourful, with friendly stewards, easy baggage check and boarding, and a smooth take-off. After about 10 minutes in the air, the plane explodes with no warning whatsoever.
Windows NT Air
Just like Windows Air, but costs more, uses much bigger planes, and takes out all the other aircraft within a 40-mile radius when it explodes.
Windows XP Air
You turn up at the airport,which is under contract to only allow XP Air planes. All the aircraft are identical, brightly coloured and three times as big as they need to be. The signs are huge and all point the same way. Whichever way you go, someone pops up dressed in a cloak and pointed hat insisting you follow him. Your luggage and clothes are taken off you and replaced with an XP Air suit and suitcase identical to everyone around you as this is included in the exorbitant ticket cost. The aircraft will not take off until you have signed a contract. The inflight entertainment promised turns out to be the same Mickey Mouse cartoon repeated over and over again. You have to phone your travel agent before you can have a meal or drink. You are searched regularly throughout the flight. If you go to the toilet twice or more you get charged for a new ticket. No matter what destination you booked you will always end up crash landing at Whistler in Canada.
Linux Air
Disgruntled employees of all the other OS airlines decide to start their own airline. They build the planes, ticket counters, and pave the runways themselves. They charge a small fee to cover the cost of printing the ticket, but you can also download and print the ticket yourself.
When you board the plane, you are given a seat, four bolts, a wrench and a copy of the seat-HOWTO.html. Once settled, the fully adjustable seat is very comfortable, the plane leaves and arrives on time without a single problem, the in-flight meal is wonderful. You try to tell customers of the other airlines about the great trip, but all they can say is, "You had to do what with the seat?"
The best all around operating system is Windows 7 64 bit. Depending on your needs, one of the many Linux Distro may be just as good. Ubuntu is one of my favorites as well as Linux Mint. One of the nice things about Linux is it is free to download and change to your likings. There is also plenty of free software to use on linux machines. The big drawbacks to Linux is lack of proprietary game play if you are a gamer and a hard to set up media center, something Windows 7 easily accommodates. Windows 8 lacks the Windows Media Center and sort of messed up attempting to tackle the tablet and desktop computers with the same software. Windows 8.1 made is somewhat better by allowing the desktop as the default screen vs. the tablet touch screen, but I will wait for Windows 10 to come out and see if they got things squared away.
Depends on what you want and how much experience you have in an operating system. If you just want to use it for your personal needs go for the one which you have used so that things become a little easier. It is better to use something you rather than start from scratch... Windows, Linux, mac all are good!!
Microsoft Windows 7 or Windows 8.1
Linux crashes excessively because, unlike Windows, Linux is a 32-bit system. Windows is a 64-bit system, meaning that Windows has twice more memory. More available memory means more available performance. The more memory available the further away are the errors. <
