Kinde + supabase

Which is the best way to implement supabase with Kinde?

This method looks like the users id directly syncs with supabases user_id? - https://kinde.com/blog/engineering/kinde-with-supabase/

This method looks like it keeps the id from kinde seperate from supabase - https://youtu.be/E9sN9Wol3GI?si=cOl66FLgIxMuQ0OU

Am I correct in my thinking?

Is one way better than another? The blog seems like the way to go here?
