I live in Germany and I'm a Bochum fan. I watch the Bundesliga most weeks, at least the highlights. I don't agree that they all just use Gegenpressing, but they certainly almost all play in the transitions much more capably than other leagues. IMO this has a lot to do with the quality of defender in the Bundesliga, not just the tactics/coaching. I remember years back everyone going on about Man United being stupid to get rid of Chicharito becuase he was scoring for fun at Leverkusen and I couldn't help but think "yeah but 15 of his opponents have basically 2nd league quality defenders". If anything I think Löw, Klinsmann, the class of 2014 and Manuel Neuer have all had just as much of an impact with their technical revolution, meaning defenders and goalkeepers are more likely to be better on the ball than off it.
You're right to an extent that Bochum are "built" for the Gegenpress, in so much as they possess lots of players with a great work ethic, but that's not all that matters. You need the technique at speed, decision making and above all, elite fitness to pull it off IRL every week. Bochum have had their fair share of players made of glass in recent years (becuase it's what they can afford). And technique is not something I'd expect to see in abundance at the Ruhrstadion. I get your angle but Europa League with their 22/23 squad is really unrealistic.
Also you've made my point for me when you talk about rest defence. Why didn't my mate concede 3-4 goals a game? IRL teams would be smart enough to pick Bochum off even if the are being intense. Or like you say, both teams press like hell and the result becomes a coinflip. Either way it proves my point that my mate's result shows there is a meta and that it disappoints me that I'll always have that temptation, when playing a completely different style, to flip the Gegenpressing switch in order to start getting success. Like I said, I'm not overly arsed that this is the case, but I'd prefer if it wasn't.
