Airline comforts and terminal transfer issues aside - your friends route has two long segments of 8 hours and 10 hours. Your route has an ultra long of 14 hours and a relatively sort segment of 4 hours. I would prefer two segements where the flight durations were closer together, as I have a hard time getting solid sleep on a plane.

With the JFK-HKG leg you have a shot at some significant sleep, although a 9:15am departure time that does not really sinc up with body sleep time. The TATL route flights are really a double redeye and might be easier to adjust to.
