Fanny pack or hipbelt pockets?

I'm seeing ads for ultralite hiker fanny packs. They are touted as the perfect place to keep snacks, cell phones, small essentials, that can be worn in camp or on the trail.  Is this better than the hip belt pockets on backpacks?  I use a Zpacks Arc Blast, and the hipbelt pockets are more than generous.  Are people finding it more versatile than hip belt pockets?  I've used them for short hikes, but I'm not convinced of their utility.

I’m able to fit pretty much everything that I might need throughout the day while on the move in my hip belt pockets, pants pockets, and in the side pockets of my pack...except for a larger camera. So I do take a ZPacks Multi-Pack for that purpose and it often ends up carrying a few other items as well. If I used a compact camera though it would not be needed as that could fit in a hip belt pocket.
