In the next.js guide, https://supabase.com/docs/guides/with-nextjs#bonus-profile-photos

from.download()

is used to generate a url for displaying avatars. For public buckets is using

from.getPublicUrl()

better? Are there any benefits to using either of thsse?

I would use getPublicUrl for public buckets. It does not generate a database/storage call (just builds the url) and the file is then only downloaded when you use the url.

Okay...
