Why shouldn't I compile with VIS and RAD on 'Fast'?
I know that there HAS to be a catch because if there wasn't then why would they bother having a normal setting

Fast compile is a quick way to test stuff. Expert spends more time, makes r_speeds (or whatever they are now) a bit lower because it calculates better values.
In short, expert looks better and should be done on final compiles or when you feel like doing it. Fast is for tests.
