CentOS 7 is newer, will be maintained for longer period of time so for new VPS i would suggest going with CentOS 7.

Centos 7 introduce you to a new friend that many people hate called systemd :) as @hostens said, it's newer and (should be) better, although i think centos 6 is still supported until a couple of years from now.

CentOS 7 for newer kernel and improvements and less neglected by upstream Redhat for timeliness of yum updates compared to Redhat 6/CentOS 6.

I will keep this advice in mind but still using centos 6 on a VPS.

What is really systemd? on Centos6, it is system?

I don't know why you don't like systemd, I tried centos 7 but seem it is not for me, very hard to use, its commands are different from Centos 6 while I was familiar with centos 6 for months.

It has better performance if I move to Centos7?
or it is just small improvements.

Newer versions always give you better improvements.
I used this version but felt difficult a bit and I had to reinstall my VPS to use Centos 6
there are a few software could not install on Centos 7 or i didn't know how to use commands with this version, more familiar with Centos 6 :)

Personally i prefer Centos 7 again as mentioned better improvements and fixes, though most are aware that with any new versions of any OS there will need to be improvements to the software we use so when upgrading make sure that all your software you use works with the most current Kernel / OS version.

its all about swings and roundabouts - new versions better improvements vs functions and features from the software we use that are not fully updated to support the latest OS releases. a good chance to wait until software you use is fully support before the official upgrade on any live system

system is init system , they change inetd, cron, WatchDog, chroot, mount and fstab.

Centos 7 it's new software, Centos 6 stopped full updates 10 May 2017 , so try install centos 7 in virtual for example KVM and use time-to time, then reinstall your Centos 6 to Centos 7 . You can also upgrade from Centos 6 to 7 , but I recommended reinstall. (do backup before any change)

I would stick to Centos 6 than go for the upgrade to Centos 7.
Centos 6 has been stable so far so there's not a need to upgrade yet. I

I have heard that many people have opted to revert back to Centos 6 as there's a lot of command changes.
However, it's a matter of time before Centos 7 will be stable so get ready to familiarize with systemd.

When you want the more latest version, go with CentOS 7. However, I had issues with the new thing systemd. Its pretty hard to adjust into it from the way I used to easily with CentOS 6. However, my decision is 50-50. 50% because CentOS 6 is still supported and way more user friendly and easier to use. I am still using CentOS 6 but due to fast paced generation. We should start adjusting and familiarize ourselves with CentOS 7 systemd soon.

I agree that it's better to adjust to the newer version earlier than later. You would not want to wait till the updates are totally stopped and no more support is given for CentOS 6.

As a cPanel user, you consider updating the data to CentOS 7 for safety and security reasons.

End of the day both work well, it really depends upon your requirements and if you care that updates for CentOS 6 end by 2020. Keep in mind that CentOS 7 is a newer OS and also has additional security features.

CentOS 6 will be available forever however updates and support will stop in 2020.

My company will use 6 for shared and resellers plans until cPanel no longer supports it and I'm forced to upgrade to 7.
