Having flown both, I'd say “not at all”. Each has their challenges. But please do note that somewhere in the first few pages of the Airbus FCTM is the helpful advice that, when in direct law, one simply flies the aircraft like a conventional jet transport.
What do you expect that pro tip might mean to somone who has never done that?
i never really loved the manual flying on FBW, but then again I never HAD to, it was always done for skill retention only.
