It has better than winglets. Raked wingtips will always be a better choice over blended winglets. Raked wingtips have to be designed in from the basic wing design. Blended wingtips are if you are retrofitting an existing design. P8 wings are new, so the raked wingtips are designed in from begining. 737 wings are legacy design thus winglets are the answer. Raked wingtips perform better in general.
That’s very interesting, thank you. I haven’t seen a planform view of the wing, I’ll look it up, though.
