I’m no expert on European plumbing, having spent 2 years at an airbase in Germany. I suspect that there, as they do here, the lowest bidder won the contract. 
Having said that, I also have some gripes about our “modern” toilets that seem to match those of the OP and I was born here.
My house was built in 1955, and at some time in the not-too-distant past, the previous owner improved the house by increasing the size of the kitchen & master bedroom, adding a bath just for the MBR. The hallway toilet may not be archaic, but it does its job very well – no spashback and when you flush, an impressive display of hydraulic power whisks the offending matter down the pipes posthaste.
The new, “modern” toilet, OTOH, can be relied upon to clog at least once or twice a year. Sometimes, when it’s on a roll (insert rimshot here) it will clog several times a month. I suspect that part of this may be due to amateur workmanship when the pipes were laid, but at least twice a year I have to go outside and “work the clog” from the other end just to get things going again. When flushing, there’s never quite enough power to send everything on its way. :mad: Often multiple flushes only serve to thove the current wastepile into the one that didn’t quite escape down the pipes and the resulting logjam requires considerable plunging and occasionally chemical warfare (drano, undiluted lye, or whatever bottled vitriol is available).
The “modern” toilet must have been designed by someone with no/very small external genitalia. I believe I am average in this respect, but due to the high water level in the bowl, I must take care to sit “just so” else parts of me will be baptised in water of questionable sanitation. And it’s cold, too!
Someone mentioned padded seats earlier in teh thread. I have used padded seats for years, but finally realized whi they are a good thing, when in a fit of Scotsmanship, I replaced the old, cracked padded seat with the cheapest plastic seat I could find. This was in winter, and to save on heating, I usually keep the MBR bath door closed (and thus, cold. I realized the error of my ways when, one cold morning, I went into the (even colder) bathroom for my morning “constitutional”. When my posterior hit that seat you could almost hear the capillaries slam shut! It was like sitting on a block of ice, but not as wet.
I replaced the cheapest hard plastic seat I could find with the cheapest padded seat I could find that very day. If I need to wake up in a hurry, I’ll take the espresso, please.
