Is 1. Bd2 significantly better than 1. Ng5?

[Master Om]

Certainly, the conclusion before the last month was that 3. Ng5? only draws, and that people had been getting prematurely excited by an engine quickly finding the obvious 1. Qf6+ without caring whether it followed up with the correct 3. Bd2 two moves later. Did the most recent two or three posts in the Qf6+ thread challenge that conclusion or just confirm it?

Exactly. I did a two week deep analysis. I posted in the thread too.
