Purely for energy saving reasons, he always says that with the 42 cm the U-value is 25% better again and the extra cost would probably have been worth it. Whether that is the case is something everyone has to decide for themselves.
With ~13% more wall thickness, so ~25% better U-value with the same brick... It should be obvious that this statement is quite nonsense ;)
