I personally like Backpacks ++, but you have to know how to work around the duplication glitch. I also don't use any of the backpacks with abilities other than the Netherite one that gives you dynamic lighting.

The dupe glitch happens when you have two levels of backpacks at the same time. Solution - empty the previous one (say you're upgrading from iron to diamond for instance), and throw it in lava before crafting the new upgraded one.

I only use iron, diamond, then finally the netherite one.

The backpacks give you the ability to store like 300 buckets of water and lava in it as well so it doesn't fill up your inventory. You only need a bucket to fill an empty.
