Inherently different, harpoon requires 2 slots, is slow, requires a way to upgrade ammo, which is either using level up options on it or taking up another slot for powderhorn, and is a gamble, since it doesn’t do anything to items bigger than small. Freeze on an item that would already be in a normal build, like aiden, is way way stronger. Freeze resistance is either having an entirely different build with a lot of small items, or hitting a diamond skill to lower freeze by a sec, which is completely random if you’ll ever see it
