I am flying the Hawker and would rather take the Excel, because:
I can stand up straight when I´m taking a p*ss in the Excel, not in the Hawker. I am 1,80m.
The Excel brakes down more often, giving you less flights. With the Hawker you have to cover for broken XLs
I don´t care if I´m flying M.75 or M.78
The Excel will keep you away from Russia a bit more often.
You´ve got the wonderful external cargo compartment.
Hey, I should call Cessna to be their salesman!
