An awful lot of outstanding technology lost due to one critical defect. For those of you who have never flown a 225 this will be lost on you.
Only the envelope protection and autopilot DB.
The rest of it was not so special. The fuel system was from 1960s, the engines were old and smokey, the rotor system was nothing really new with no icing clearance etc. All in all, the 175 made it look very old.
