Can you give me a better understanding on how the Cores Per Socket and CPUs work with the VMs, I know it has changed a bit over the years. Is it better to have more Cores Per Socket and less CPUs? Any clarification you can give would be appreciated. Thanks!

Here is what I have:
Server #1
6 CPUs
2 Cores Per Socket
3 Sockets

Server #2
8 CPUs
1 Cores Per Socket
8 Sockets

Server #3
4 CPU
1 Cores Per Socket
4 Sockets
