The King Air 260 leads, topping 7 of 7 compared metrics.
Cross-shopping the Beechcraft / Textron Aviation King Air 260 (introduced 2021) against the Piper Aircraft M600 (introduced 2017) is a common decision, and the two sit closer on paper than the badges suggest. Both are turboprops, which makes them natural cross-shopping rivals. The clearest separation between them is cabin capacity, where the King Air 260 carries more passengers.

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 260 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.
Which should you choose?
On published specifications the King Air 260 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The M600 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
