I haven't watched many workshops but @PlebLab has some workshop superstars: @supertestnet always entertains and makes it really easy to get to the point, @bitcoinplebdev explains how foundational software works really well, and @BlueSlime is incredibly thorough and deep.

If I had to pick a favorite, I'd rank them by how much I was surprised to learn. @rodarmor's Ordinals Workshop is probably near or at the top.
