For example, you could do Decin (Czech) to Glanerbrug (Netherlands) in 12.5 hours with only 7 changes, all on RB/RE and S-Bahn trains.
Of course, that's still going to be a long journey, but you can break it up anywhere you want and stay at cheap hotels in random German towns along the way that you otherwise would never have considered visiting!
FlixBus seats, when reclined, are on par with economy seats in any airline I used. But FlixBus seats have considerable more legroom.
Also the bus takes breaks on journeys that last for that many hours.
Even some of the direct FlixBuses Berlin–Hamburg (3.5hs) take a 5min break at a petrol station somewhere in the middle of the journey.
Buuut... I was on a school trip to the UK once where I spent 13 hours on a bus and I remember hating every second of it. Well, we'll consider it :)
