You still have to make network calls to obtain public key (JWKS) to validate token signature. Unless you are using shared private keys. With userinfo you will know if token is invalidated or not. I guess it also depends on use case. If you are in domains such as banking with elevated security requirements, then probably you want to hit userinfo endpoint else you can continue with token validation with cached or stored keys.
