I think I am more of a night owl, because I am definitely not a morning person. My kids are up too early for my liking, so I really dislike morning. At night I will definitely stay up watching movies later than I should, but not past 11:00 or 11:30. If I had my way, I would go to sleep at 10:00 pm and not have to get up until 8:00 am.
Usually I am a night owl. I get insomnia and am awake until 4 or 5 am. DS tends to wake up at the crack of dawn.
There was a year where I worked from home before I had kids. I fell into a schedule of going to sleep around midnight and waking up around 8... so I guess that is more night owl. Now with kids I go to sleep around 10:30 or 11, and wake up sometime around 7 (around when my first kid wakes up).
By nature I'm a night owl but I really wish I were a morning person. I do envy those who can spring out of bed at the crack of dawn and be chipper/ready to go for the day. It would fit with my ideal routine / lifestyle a lot better but I'm just not there.
