Agree with 5.7
Regarding 8.0 in general: Does anyone know the current state if available connectors have been upgraded to the new standard authentication-plugin?
With the Jump from 5.7 to 8.0, MySQL changed the standard authentication-plugin for new users from "mysql_native_password" to "sha256_something", and i know that a lot of people had trouble with that.
Another change from 5.7 to 8.0 were new keywords (e.g. in 5.7 "groups" was not a keyword, in 8.0 it is --> notice the "s" as in plural), which caused working software to break (i myself had that problem. Our Software-Provider solved it by escaping the keyword)
