A solid masonry house, as the name suggests, is solid, and if well built will still stand in 200 years, I don't necessarily believe a prefab house will do that. I would always build stone on stone.
Sorry, that really is not a well-founded statement...
Take a look at the oldest houses in your town – they are probably half-timbered houses, right?
What do you think the load-bearing structure of a half-timbered house consists of?
Could it possibly be wooden studs?
One should not compare apples and oranges here; I wouldn't want a US-American "chipboard box" either, but I bet our high-quality timber frame house will last at least as long as a "solid" built one. I will deliberately leave aside the healthier indoor climate and better thermal insulation at the same wall thickness here...
Just as a thought-provoking example: Two years ago we experienced a noticeable earthquake at friends' place in Switzerland. Damage to their timber frame house: none – The immediate neighboring house ("solid house"): clearly visible cracks from the ridge down to the height of the first floor.
In the end, it is purely a gut feeling which type of house one builds, but one should please also accept other builders' decisions and avoid badmouthing their house concept.
