Perhaps sleep quality doesn't always directly relate to how rested you feel afterwards? I've been having a very varied amount of sleep for the last few months due to a newborn baby. It can definitely happen that a good 5-6 hour stretch (the max I get these days) leads to me feeling more tired. Sometimes running on fumes actually feels easier and more wakeful.
