Ok, I just added the "Deathmatch" to make this seem a little sexier. It's been 4 nights or so on monophasic sleep and I feel like I have a good basis to compare them.
Overall, there are some pretty big surprises. The most significant is that I'm back to sleeping a full 8 hours. The first night I slept only 5 hours, but from there it ramped up. What? I was totally expecting raw food to pull through for me here. I also feel more tired during the day! It's only been a few days, so maybe I need more time to adjust, but so far I feel like I'm less alert.
The best part about monophasic sleep, not surprisingly, is that my day is uninterrupted. This gives me a lot of freedom to do whatever I want during the day without worrying about a nap. I still occasionally think "Wait... when's my next nap?". Right now I live about 15-25 minutes North of most activities. If I want to take a nap at home and come back, that's 1 hour to 1:40 of driving time I have to factor in. Because of this I would often have dinner with friends but then go home instead of going out. I would also schedule things at strange times to avoid messing up my naps. Occasionally I would throw caution to the wind and skip naps or push them around, which would inevitably mess up the schedule.
