What would be my better operating system?

I'm assuming I will get biased answers on this, but I'm asking anyway. I'm 18 have been using a pc my whole life. I like almost everything about it, especially Microsoft office. As for mac, I have used one in school and they seem difficult to operate. I have heard good things about mac like how it is resistant to viruses and how many people never go back to PC. Other things to consider: I absolutely love Google, but it doesn't seem to have a preferred OS. I use ipod/iphone and i find them and their apps convenient. Lastly, my preferred email would be windows live/outlook. Judging on that information would it be more convenient for me to switch to mac?

Macs are better, i myself prefer windows because i one thing. I like to game. If you don't play games that need windows.id go with mac

Go for Mac… Less threat to virus… Also check windows 8

So first of all there's not a best operating system.

I personally would tell you that linux (debian/wheezy) is a great os.
But why would I do that? It's because for me it is.

Generally the best os for someone is the os he needs.
If you often play pc games you will stick to using windows.
However if you're mainly doing thinks in the internet or working with office programs linux or mac will be an alternative.

But since you are mainly using microsoft programs you probably should stick to it, just because you are used to it unless there are things you really do not like about it. And it takes time to learn how to use another os, so if you are not willing to spend that time better don't do it.
(Never change a running system:-)

And about that google thing. Google has developed a linux based OS (chrome os).

Its not a matter of what is better, mac and windows each have their own strengths, personally i prefer windows, i have never liked the mac operating system, go for whatever one you are most comfortable using, it is true that there are less viruses for macs but there are starting to be more written for them, if you use a decent antivirus and antimalware program and use a bit of common sense windows is absolutely fine and safe enough to use

I would like to suggest you, use Mac OS because it is less virus affected. There are lots of advance applications on Mac i.e not available in other OS. I'm using Mac from last 7 years without installing antivirus on it and it is running in tip top shape.
