The end result is Charles II of Spain:

Charles’ reign has traditionally been viewed as one of decline and decay, a foreign ambassador commenting in 1691 “it is incomprehensible how this monarchy survives”.

Earlier the Habsburgs were famous for making good marriages that led to them inheriting additional territories. "Let others fight wars--you, happy Austria, marry." But the Spanish Habsburgs didn't keep to that tradition. The Bourbons took over Spain after Charles II's death and that was an improvement for Spain and her empire.

Meanwhile the Austrian Habsburgs continued until 1918, and the son of the last Habsburg ruler, Otto von Habsburg, was a well-respected European statesman.
