To be honest, the reason I made an account on Digital Ocean, is to play around with CentOs and learn how to manage my dedicated server because I pay a lot for a company to manage it for me and I want to be able to do it myself.
But after I tried Centos 6.5 and Centos 7, I will drop my droplet for one more time and I will try Debian.
I always thought CentOs was the best for web servers, but after I played with CentOs I found out that is too complicated and too outdated.
I have LinuxMint on my laptop and LinuxMint and Ubuntu is based on Debian. I will give Debian a try.
The ONLY problem I can see about this, is the CPanel is ONLY working with Centos and not with Debian but there are other options for example Plesk etc.
I'll try Debian and if I will be satisfy with it, then I will stick with it.
I prefer to managed my dedicated server 100% on my own using Debian, than manage it 80% on my own using Centos.
I came to Digital Ocean to use and test various OS for servers. So far I am NOT satisfy with Centos. I will try Debian.
Now, let me give you an advice: the BEST Os for your web server will be the Os YOU will know better and you can handle with it. In my case I gave up with Centos, I will try Debian ,I am using LinuxMint every day so I wont have problem with Debian.
On the Internet you will find many people to suggest the best one is Centos, other will suggest best one is Debian, others will suggest Ubuntu as a server etc etc. You will NEVER know for you if you don't use those Os and play with them, test them etc etc etc.
Some people outthere say it's more stable and more predictable with CentOS
but I think they talk about RedHat, i'll choose to implement Oracle Linux for the maintenance, the possible pro support and their ksplice.
I love Debian, but they are slow to patch and move forward. Instead i'll choose Ubuntu for their predictability and their possible support too.
others sources might help to take a decision :
