I believe that the XS is optically identical to the DA40 Ltd, so I wouldn't take that for a given.
Now, I don't have the 40 (any of them), but from what I see they are great performers. I'm very happy with my FA43 and don't plan to get a 40mm, but I am fairly certain I wouldn't get the 43 if I already had a 40 either. I would say the that two are
different rather than that one is better than the other.
I do have a DA70, and I see little reason to get an FA77 (unless one should show up at an exceptionally good price, of course...).
But as always, if what you really want is an FA43 then go get it if you have the funds. I would recommend looking on the second-hand market.
