For a high-end component, maintenance is the way to go. For lower-end groupsets, replacement can make more sense. A brand new 10 (£/$/€) set of jockey wheels for an entry-level derailleur is a far better net use of finances and time than a repair. But the opposite may be true for pro-level kit where jockey wheels may cost considerably more.
Good that your not one of those idiots that buy everything new .Maintainance is the way to go until it’s wore out👍
