Shibu onsen vs Kinosaki Onsen

How do you compare Shibu onsen vs Kinosaki Onsen? I had been to the latter, I think 1 night is enough, the town was nice even during late spring but really wasnt impressed with the variety of onsens there. Most are old and in need of revamp, except for 1.
Not sure how Shibu onsens are like in comparison during winter? Because if I am staying overnight, it will be because of the onsens and the monkey park, the town is just a bonus.
