I like a pack that, like the Fiamma can be unzipped, & opened flat on the ground (like a book). When you are looking for a specific piece of kit, a top loader is at a disadvantage. I also like a lot of compartments & don't mind the cords, good place to tuck the wet rain gear/socks when the weather clears.

I see you've picked a top loader, for comfort reasons. Comfort is the no 1 consideration, good choice ! Did you choose the "Atomic Tangerine"?
