Last time I took such overnight train in Europe was Frankfurt to Copenhagen in 2013 by DB, and it was nice and comfortable. Trains always have more leg space and moving around areas than an airplane. With budget airlines they are trying to cram in as many people as possible, almost to the point of making you feel claustrophobic. With trains there is no hassle of going to the airport, as they are mostly around city center. Also, I found people to be more friendly in trains, unlike in airplane, where most people have their headphones on, and do-not-disturb expressions.
