The little favorite is a quiet bow. The Super Shrew longbow is a extremely quiet bow. I've killed deer with both the Lil Favorite and my Super Shrew Samurai on quiet nights and there's not an issue with how quiet either is.
I personally like longbows better than recurves. The Lil Favorite is a very well behaved little bow. The grip from one Shrew bow to the next is the same; so you have the same comfortable and easy grip to hold.
From a personal standpoint, if I was going to have only one Super Shrew, it would be the longbow version. However be warned, they're like Lay's potato chips, so you may as well just order them both.
