I have similar results and opinions. I feel that there is some kind of "back-end processing" that happens during sleep that is crucial for learning. Also, my sleep tends to be better when I'm doing some kind of workout regularly, although I need to sleep more. If I'm not working out, I can get by easily with 6 hours but if I am, absolutely need 8 hrs min. Makes sense to me since a lot of repair, healing and growth occur while sleeping.
