If the toilet is good then this will be the best jet for owner pilots.
I have to disagree here. Most owner/pilots I know don't like the aircraft toilet being used full stop, certainly no no.2's! The Falcon 2000 parked next door to our jet is a prime example - the owner (who is also co-captain) wont let pax use the toilet unless in an emergency. He even does not offer them coffee on board so they wont have to answer the call of nature. The average flight duration they operate is probably 4.5 hours.
Whether this is from a cabin cleanliness point of view or just to avoid paying for a toilet service who knows...
