Which Should You Buy?

Bottom line: Choose the Baron for a fast, refined twin with Beechcraft pedigree and strong performance. Choose the Seneca for an affordable, practical six-seat twin — a long-serving workhorse at a lower entry point. Choose the DA62 for modern efficiency — composite construction and jet-A diesels with low fuel burn and five-to-seven seats. On safety all three are piston twins offering engine-out redundancy but, like any light twin, rewarding engine-out proficiency; the differences are performance, cost and efficiency, not safety class. Refined performer, affordable workhorse, or modern diesel.
