For this particular picture, I think sinc (Lanczo3) is the best. It managed to preserve lots of details but minimize, almost as much as 'none', but also kept those stair-step side-effect down.
Cubi-resized result also has lots of details but looks soft compare to 'sinc'.
Anyway, this is a computer-generated image. It would be interesting to see how these algorithm do with the real-world pictures.
