Unfortunately comparing the Saab340 with the 2000 is a little like apples and oranges.
The 2000 was a truly next generation aircraft. It incorporates many of the features one would expect to find even on a new build aircraft today! FADEC, Full modern EFIS, Much simplified systems, first class ergonomics to name but a few. As well as this, real 31,000 feet ceilings and a TAS of around 370 kts!
These differences meant that it could not be simply compared to it's ancestors the 340A & 340B.
A Saab 340C was in the works. This 34 seat Cousin of the original Saab's would have had all the advanced features, and very importantly a common type endorsement of the 2000! Now that would have been a fantastic fleet mix.
Ultimately, the reason for the 2000's commercial failure was that it was born into a world of 50 seat regional jets. Despite superior field performance, and far better operating economies, and very competitive point to point times over 300 mile sectors, it could not however compete with it's sexier and propellor less rivals in the European and North American markets.
The 340C was stillborn, and Saab ceased building regional turboprops. a crying shame.
