This is an often repeated, but completely false observation. The reality is that Cirrus and Diamond dominate the market for new piston singles [1]. If you want to buy a piston aircraft with the latest safety features, performance, comfort and training, then Cirrus is the number one choice. Cirrus has the number 1, 3 & 6 top selling aircraft (all have the same airframe and avionics with different engines) and thus dominates new sales.

The Cirrus SF50, which was the subject of this story, is the top selling light jet by a large margin too for many of the same reasons. It provides the best safety features, technology, comfort and price - though admittedly it does sacrifice performance to achieve the other attributes. This is aviation and everything is a collection finely balanced trade-offs.
