Arch wiki page on reflector states that:
Make sure the resulting /etc/pacman.d/mirrorlist does not contain entries that you consider untrustworthy before syncing or updating with pacman.
The question is, how should I know if a mirror is trustworthy or not?
I’m just using the kernel.org mirror for now but I should look into unis too. Good idea.
I hope you find one that works for you! 😊👍
