I find the amount of sleep is not as big of a determining factor than when I have to get up. If I go to bed at midnight and have to get up at 4am, I'll be ridiculously tired and beat the whole day. It will take everything to get out of bed. In travel situations where I do need to get up that early I'm better off saying up and just sleeping on the bus/plane/car. If I go to bed at 8am and get up at 12pm, I'll be more refreshed. In the 1st scenario I need an alarm to wake me up and it will interrupt my deep sleep. In the second scenario, I will wake up on my own or be in a lighter sleep.
Though I imagine after a while only 4 hours would take a toll no matter what. When I'm on night shifts I hit a point where I no longer wake up automatically at 12pm but more like 2 or even 4.
What would be interesting to try is a system where I only go to bed when I'm tired, and get up automatically when I wake up. Basically completely ignore time and let your body tell you what it wants. I think there was a study on this actually. Basically you stay up and do stuff like you normally would for about 36-48 hours, then sleep for about 10. When I'm not working I actually have to force myself to sleep because it will be 4am and I still want to do stuff. Whether I'm doing stuff around the house, coding, watching TV etc... I could probably easily stay up like another 8 hours and then go to bed half way the next day.
Though light/darkness has a bit of an effect too so idealy need to stick to a pattern that is in sync with that. In summer there's barely no darkness, maybe only like 4-6 hours of it, so I could see myself only sleeping like 4 hours at a time. In winter it's dark practically all the time except for a small period mid day, which is either spent sleeping from night shift, or spent inside if I'm working day shift. Never actually see sun at all unless it's a day off and even then if I sleep in I probably miss it by the time I shower and stuff. I find in winter I'm generally more tired and sleep more on days off and it's probably because of that.
