My favorite awakening is ope ope no mi. (Never watched film gold or stampede which featured filler devil fruits) cause it can pierce through anything no matter how hard it is like gamma knife and can even create a counter shock once it bypasses the skin. Katakuri awakening is pretty better than doflamingo as he can spread mochi around and can make his enemies suffocate and even summon donuts from air and bring arms out. Now about the hito hito no mi model: nika. We don’t know too much about the awakened abilities so far. Tbh it looks weaker than gear 4 snake man and boundman. We know that it allows him to manipulate the environment and others by turning them into rubber and has much more freedom (freedom was actually here in gear 4 where luffy was able to redirect his punches) like automatically activating gear 3rd and 4th and turning giant. When we know a lot more and see how more powerful it is, maybe I’ll change my opinion on ope ope no mi.
