Should I use Centos 7 or Centos 8 on my VPS Server for Plesk?

I asked this question on serverfault, but I was told to ask it here.

I’m going to buy a VPS from a company. It asks me if you want to choose Centos 7 or Centos 8 when purchasing VPS. From what I’ve researched on the internet, there is no difference between the two. But I didn’t really trust what was written on the internet. If there is no difference, why would Centos 8 come out?

My question is, should I use Centos 7 or Centos 8 to install Linux VPS Plesk?
