Which mission suits which aircraft
Both aircraft are built for regional and short-to-medium legs, so outright range rarely separates them — the call leans on cabin (the King Air C90GTx seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
