The skyliner has reserved and comfortable forward facing seats with tray tables and extra space at the end of the car for luggage storage etc etc.
I had forgotten about this, but it is a very good point. If you will have much luggage, the extra yen for the Skyliner or Airport Limo Bus is well spent. The "Expresses" and commuters will have VERY limited space for bags. If you search back through old threads on this forum, you will find a couple of lengthy discussions about baggage and Japanese trains.
