Favorite backpack?

So, what’s your current favorite? I still have a Jansport external pack I’ve had since the 1980’s which still works fine, and even used it when I took my nephew backpacking in the Sierra Nevada this past Summer. I also have an Osprey Exos 58 which I’ve used many times over the past ten years or so. My current pack is a frameless model from Nunatak Equipment called their Bears Ears model. It’s perfect for me since in the Sierra trails I most frequently backpack in all require a bear canister, and the Nunatak pack is fitted with a canister loading system on the bottom, which keeps the center of gravity nearer the waist, and makes for much easier carries.
