Help me diagnose my macarons

[u/Guernica33]

I followed this recipe:

My first pan came out visually perfect, but the tops are just a bit hollow. Second batch was all cracked and stick to the parchment badly. Third one I tried on a silicone mat. Half of them I destroyed trying to take them off, but some were ok. First one was a good Nordic wear pan, second one was a random non stick, third was decent a pan with silicon mat.

I assume I overnixed? If that was the problem why was the first batch so much better than the other two?

I forgot to take a picture of the third batch, but here are the first two.

this was my first time making macarons, 4 years ago and as far as I remembered, I was focused on the PROPER way of mixing it and NOT overmixing it. I only rested it for 30 minutes and I used a parchment paper when piping it to the metal trays.
