I think there's a lot of "it depends" going on in these arguments so it's hard to say. I've worked on cars on both ends of the spectrum so this is just my experience.
My main concern is long-term maintainability for imported vehicles by me personally. Even though I'm a software and electronics nerd, I still don't have all the things necessary to maintain a modern vehicle, nor do I want to be re-manufacturing PCBs or replacing surface mount components. So once any one of the dozens to hundreds of boards goes bad, you have to find a replacement, and you also have to hope that the of EEPROM is in the right state for your car in regards to error codes and calibration so that you can actually use it.
One example from a 2012 Toyota Crown, replacing some trim on the steering wheel tweaked one of the sensors out of calibration. During recalibration, part of the radar braking system failed to calibrate. The car is perfectly fine in 99.9% of parameters, but the computer has disabled every computer assist system and put others in limp mode until this one can be calibrated. No traction control, stability control, cruise control, ABS, magnetic suspension, all stopped. The car handles like a truck now. That's a tough problem to solve, and a really annoying one too, since the car would work at 100% capacity if only this sensor would calibrate. Dealer can't fix it, importers can't fix it, I can't fix it.
Contrasted to more rudimentary cars, I can pretty much fabricate or repair any part I need to as time goes on. As fewer shops will work on these cars as well, I pretty much need to be self-sufficient, so simpler is better.
So it's not about reliability, but maintainability, every car will fail eventually. Not everyone lives in the middle of a city with a dealership nearby, and in my experience not even dealers can get some of these parts anymore. I can't even get parts for a 2007 BMW from my dealer anymore.
