Just found this thread from a while back. I play recorder and now have three, sopranino, soprano and alto. I also have tin whistles. I go back and forth between them all but really prefer recordr and am learning most of my tin whistle tunes on recorder. I like the sweeter tone of the sopranino in the high notes. There are some keys where its easier to play tin whistle but one recorder can play in several keys more easily than one tin whistle.
