I didn't know the latency was better on Daisy. Is that published spec or from experience? They're both M7 SOCs as far as I can tell? I am trying to decide now

I didn't know the latency was better on Daisy. Is that published spec or from experience? They're both M7 SOCs as far as I can tell? I am trying to decide now between Daisy or Teensy for a piece of music hardware I have an idea for. The decision will probably be more about developer experience (so tooling, support, etc.) but I'm at step one on the journey and am having a hard time telling them apart.
