Hi, there !
There is absolute no way to compare a CJ1 with a 350.
The 350 is more expensive in the normal Operation, but you have an aircraft which is able to bring up to 8 passengers with luggage and full fuel to a 1200 mile destination.
Try this with an CJ.
Sure, the CJ is able to fly higher and propably a bit faster.
This decision will mainly depend on the Companies or Owners special needs. Have flown the 350 for quite a while. We had a lot of passangers to take on the trips and had also a lot of 3 to 4 hours trips. Amazing little aircraft concerning Range, Pax and Fuel.
