Which mission suits which aircraft
The DA42-VI is the stronger fit for regional and short-to-medium legs — its 1,020 nm of range removes fuel stops on those legs. The Seneca V, at 828 nm, is better matched to short-haul and regional hops, where lower trip cost counts for more than outright reach. If most of your flying sits inside the Seneca V's range, the DA42-VI's extra capability is range you pay to carry but rarely use.
Which should you choose?
Choose the DA42-VI when nonstop range is the deciding factor, and the Seneca V when cabin capacity and payload matter more; the Seneca V holds the cruise-speed edge.
