Intel or AMD, which are the best for Hosting and Virtualization?

[white knight]

I would not go for any specific Ryzen model. Because I am not good with processor. But I will tell you this that they are the ones which are best with your requirements.

And indeed for virtualization you will need more cores. 4's won't do. Forget about servers in desktop home computers if you are doing something with virtual machines then you will need more cores.
