I tend to take the day flights, but that's because I'm too tall to really sleep well in IB's J seats. It's also a bit annoying to try to get into your hotel room at 10am or whenever...
But you certainly won't miss much by eating dinner in the Madrid lounge and sleeping most of the way to your destination.
