Says Cent Os for me hope its easy to use as I am still getting used to mint after a month or so and it's my first time on linux.
I was windows before linux but it gave me to many head aches with broken updates all the time, you know some times it felt like bill gates did it on purpose
frogbreath, if you're still getting used to Linux Mint, be prepared for a culture shock when moving to CentOS. I had been trying to learn the OS for almost two months, then as Windows 8 was coming into Consumer Preview, was invited to be a Moderator on the now dead W8 Forum & accepted. That effectively ended any time left for CentOS, and thankfully so.
Linux Mint is as close as a drop in replacement for Windows as it gets, so if you're still learning, my advice is for you to stick with the distro you're running. There's boatloads of assistance for Mint users compared to little when I began over 8.5 years back, here & on other tech forums, as well as articles dedicated to Mint usage. Here's a popular one that assists many with setup & part of the learning experience. Should you hang in there, things will become more natural, although like myself & others, you'll never know it all. That applies to any OS, even non-Linux ones. The complete manual is in the download link below, you have to select your distro edition & type (2nd link).
You'll get the hang of things only with the time you devote & experience, just as all of us Linux users has. We can assist when needed, yet there'll be times when you'll have to dig down deep to find answers (Google is your friend ), when there's no obvious answer or no one can address your issue(s). Just keep in mind that every Linux user here & all over the Web has been in the same place where you now are. Keep on digging & don't let bad days get you down, rather make notes of what went wrong so that the same mistake is not made twice.
Finally, I'd like to share one last article with you, as I have many other newbies to Linux. Read it, 2-3 times if you first don't understand, print by saving a copy in your Documents folder (no printer needed, just select Print from the browser's control). While the article is over a decade old, the same principles applies today. This is an invaluable resource that I turned to many times in my first year to 18 months of running Linux, about 4-5 months before I discovered Linux Mint.
Good Luck & keep on shoveling, you'll get there with determination!
