Sacarino didn't end until the 80's. The point is Bruguera was highly exploitative with crazy deadlines and tons of short stories published, even from ghost writers. Ibañez was milked down. If he had a slower pace, yes, it could still create long story albums similar to the Franco-Belgian trend, but with its own detailed style. Such as the ones from El Sulfato Atómico and Valor y Al Toro, where you can see the obvious inspration from Gaston/Spirou, but you can also spot his own style on depicting the environment. Don't blame Ibañez, but the publisher.
