The 717 is 10,000lbs lighter than the A319, if you don't need the range it's no contest.
BR700 Series engines are used on Global Express and GV family, the new G650 also has BR700 family engines. Those jets are very dependent on the most efficient engine to gain maximum range...
Do you thing Gulfstream and Bombardier would both pick a fuel-inefficient unreliable motor for their top of the line business jets?
The BR715 has the largest fan diameter of the Br700 family with 58"
It is at least as efficient as the CFM56 or V2500 in the A319, with a smaller core and a higher bypass ratio probably more so...
