I personally find this to be my favorite because I found it to be the most impactful. Particularly to myself, I ended up reaching out because I saw the jump in heart related issues (likely related to vaccines) while tracking COVID19. I reached out as I saw this podcast and was able to validate several of the items discussed via CDC data.
That put me on a whirlwind journey of being connected to quite a few different people and on conference calls with highly regarded scientists and billionaires, which I never expected -_-
There's a lot more recent and relevant information, particularly on Joe Rogan's podcast (#1747 - Dr. Peter A. McCullough):

Anyway, I don't know generally about favorite in terms of content to others, but it did put me on quite an adventure.
