The struggle is unbelievable (Ranchero vs 2 day assault)

I don't know why this is taking up so much of my brain power.

I know many people are mad at yeti for buying mystery ranch but I need objectivity here:

- I need the bag to last for life (mild exaggeration)

- I would like for it to not to murder my back and would love for it to straighten it out, if possible.

- I need capacity

- I love pockets

- and, sadly, I really love yeti :(((

The one thing that keeps coming back is that ranchero stands up (which I do like) but is that really worth it ?

Help me, please ? Has anyone had the chance to make an actual physical comparison ? If you have either, please tell me about it ?
