With bags shown I have some 32 slot bags that take up two rows each, but the second row is 6 or 8 slots only, so theres a lot of wasted viewable space on screen and it is just more scrolling down to the bottom with show bags on. The benefit is that if I'm looking for a particular thing, I generally know where in the inventory window to look to find it and it takes up less space on screen. I keep bags hidden and have a couple regular bags, an olmakhan bandolier, junk bag, crafting mat bag and invisible, similar to your apparent situation.
