AFAIK Intel patches many of those security issues in new CPUs, so performance loss won't be as severe. I don't care about power efficiency, as electricity is cheap enough for me and I'm buying computer for many years, so I'm unlikely to benefit from CPU upgrading in 7 years anyway.
Basically for me it's about:
* Security issues. They are real for Intel and performance loss is real.
* Inter-core communication latency. I don't particularly like this chiplet design for AMD, when some cores have a long time to talk to other cores. Intel seems like a safer play here. But I did not research about their HEDT CPUs, may be it's the same for Intel.
* Balance of frequency/cores. While more cores is better, I think that after 12 cores I don't really need more. And single-thread performance is always important.
* Other issues. I don't like that AMD had multiple issues with its Zen CPUs, especially with Linux. Crashes, RNG bug, overall Linux compatibility. I'm feeling like Intel takes Linux compatibility much more seriously and Intel overall seems like a safer bet for stable system.
