The Spanish have a different story on the oil company. It's hardly an advertisement to set up a business there anyway, which is what I am talking about.
Finally, I don't think being the best government in Argentine history is a very high bar to reach. You were the 7th richest country in the world in the 1920s, with plenty of resources, and now a place starting poorer than you like Japan with hardly any resources (plus getting burned to the ground and nuked twice) is three or four times richer. There are tons of examples like that beyond Japan, the governments of Argentina have been a string of disasters in terms of providing for the people and not filling mass graves with them. Taking the current government though, I'd hardly say inflation three to six times higher than Chile is a great government. But when inflation in the past has been measured in hundreds of percent I concede that this could be a reasonable government when the only comparison is past Argentine governments.
