While I agree with most of your points, you’re a bit behind the time here.
The new 5000 Series (Zen 3) AMD CPU’s beat Intel on both Single thread and multi thread performance (there’s plenty of benchmarks to find on the web on this, so don’t trust my word on this).
Maybe with the 11th gen Intel will be back on top for single core performance, but if you’re buying new right now, there’s no reason to go with Intel (apart from maybe availability).
