Which Should You Buy: Piper Aztec or Piper Seneca?

Bottom line: Choose the Aztec for a rugged, affordable twin — a tough, good-hauling workhorse at a lower entry point, the classic choice. Choose the Seneca for a more modern six-seat twin — newer systems and turbocharged options for better altitude performance. On safety both are piston twins with engine-out redundancy but, like all light twins, rewarding engine-out proficiency; the difference is era and turbocharging, not safety class. Rugged classic, or modern turbo twin.
