At one point I was using dedicated servers with 16 AMD cores, I had no problem with these, but eventually upgraded to servers with Intel with 16 Cores and 32 Threads, which were much faster (newer).
Both were equally reliable.
Our servers are all cloud now, so all differ from one another, as I only pay for the resources I need, even though they all use the same "template".
And I really don't see much difference between those servers which run on AMD or Intel.
