Is #2 technically a redeye? Arriving at 1am I'd go to a hotel (or home) and go to sleep, whereas I'd likely be ready to start the day with the other options -- certainly at 6:48am, maybe even at 5am. If BWI was my home I'd probably go to sleep a bit after arriving at 5am, but if traveling on my own dime I probably wouldn't pay an extra night for a hotel room. I might stretch out in the airport (ideally in a lounge) and sleep an hour or two, though.
The 1am arrival would be the worst of the three, in my opinion, but more because it cuts too much into the day of departure, not (necessarily) because the arrival time is so awful. And if I'm coming home and can go to my bed, it's not too bad. I would find a 5am departure worse than a 5am arrival.
