The 757 seat is indeed essentially the same as the 777; however, the entertainment systems are a generation apart. The 757 uses the same system as the DC-10, with relatively few movie choices. The 777/767 system is GREAT, with multiple choices (13 I believe) and 6 video games. If that is important, you would want to consider the 777. But, as mentioned on this site all the time, if you are going to attempt an upgrade to fly BF, be prepared, be very prepared.
