With water bottles, I didn't have anywhere to put them on the outside of my pack where I could reach them, so I'd have to stop and take off my pack every time I wanted a drink. And I'd try not to do that often, so I'd be very thirsty and gulp down 1/2 L of water every time I stopped. That's not a good strategy for avoiding dehydration.
Nowadays, I only carry ONE 1L bottle, which I mostly use for scooping from water sources.
