Your phone will be no less secure, as long as you use a good superuser app
This is factually incorrect and a dangerous statement. Your phone will be insecure, because you will have your bootloader unlocked - anyone can boot into that subsystem and access/alter the OS. It’s not a deal breaker for most, but some countries can become dangerous. Tread with caution.
anyone can boot into that subsystem and access/alter the OS
Right. I was looking at it from a malware point of view, since OP’s question “is it safe” is vague and can have one of at least three meanings. If your phone is rooted and the wrong person has physical access to it, they can bypass factory reset protection, among other things
However, most phones nowadays encrypt their user’s data using the lock screen password as the encryption key. I think this would limit an attacker’s access to user data, but don’t quote me on that
