Buttercup, delicata, carnival, and sweet dumpling are my favorites.

Many people do not even realize what buttercup squash is, or that it's even around.  All we ever hear about is butternut squash and I hate that stuff - - it has a very "dark" flavor, to me.  But to each his own, I guess.

Lots of photos at that last site.

I like to take an acorn or small delicata squash and stuff it with chopped apples and a blend of brown sugar and cinnamon.  More like dessert than anything.  Well, after all, most squash are considered a fruit rather than a vegetable.  So is a pumpkin, for that matter.  Look it up.
