OK, but what did you find after a few cursory searches? Many of the results would lead you to HN threads... where you would find that quality you are looking for.
For OpenBSD, the last threads on hn.algolia.com are from 2 years ago for v7.1; v7.5 is now out, which is a newer version by 4 releases.
I think the consensus is if you’re ok with Fedora’s arm64 package selection, don’t need external monitor or TB, shut down your computer every time instead of closing the lid to sleep, you’ll get really good performance on Asahi Linux but not as good battery life as on macOS
