Frequent Tokyo traveler here. JL is better in nearly every regard in J/F. Great hard product and exceptional soft product in J. JL's catering and service has hardly been touched by the COVID pandemic (see my recent JL F trip report for an example). HND is generally preferable to NRT, especially if you are spending a night in Tokyo/Yokohama - hard to think of too many places in Tokyo that would be quicker to get to from NRT.
