I work on this aircraft (Jetconnect international config) and I believe 1D,F now have the most leg space of all the J/C seats and of course you dont have anyone reclining infront.

The main issue with the seats in row 1 is the proximity to the galley and forward coat cupboard - which can be opened and closed several times during the flight. Quite a minor issue though and most crew are conscious of this during late night flights.
