In my case I've had this issue (advantage?) since childhood, where I vacillate between both states in 2 week blocks - 2 weeks at a time where I'll get 7-8 hours, and 2 weeks where I get approx half as much. In the latter case I simply don't get naturally tired. But it does eventually catch up to me, and then all of a sudden - bam!, I'm tired one night and naturally fall asleep say at 10pm every night. What I've found is with the poor sleep cycles I tend to be more energetic and get to solutions quicker. If the problem requires deep thinking, I can focus on the problem at hand much better, but at the same time I can make many superficial mistakes. The best I can say is it's a bit like being in a minor psychedelic state all the time, where the creative pathways of my mind are more open with a manic desire to latch onto something interesting. It also exacerbates my Asperger's-like condition. OTOH, if I am in the design process and building a piece a software that requires high conceptual integrity getting more sleep is certainly beneficial.
