Likewise, Mr. Google is my friend when left to wonderment about different fruits/veggies!
TBH my experience has been that there really is not much difference from one squash type to the other for usage/recipes, despite all the claims of differences that are made! Kabocha is a winter squash, thus the dryer sense. Therefore, if you have a favourite use for the other winters, then kabocha will probably do fine.
Bon Appetit!
