European Spanish, European Portuguese, Argentine Spanish, Brazilian Portuguese ?
Spanish, together with Portuguese, is quite useful & practical especially in Latin America, but I'd like to confirm which language is universally recognized as a better choice, if Spanish is, which kind of Spanish is better, Eur. style, or Lat. American style (it also includes a few sorts), & if Portuguese is a better choice, may I say that Bra. style seems more useful or sounds more beautiful than Eur. Portuguese. Actually, I've got 4 good textbooks (with CDs) on hand, one is about Eur.Spanish, the other is about Lat.Spanish (but I don't know which kind of Lat.Spanish), the third is about Eur.Portuguese, and the last one is about Brazilian Portuguese, perhaps I'll have to choose only one of them to learn on my own, but would you please make suggestions to help me decide on which one I should learn of all these kinds, not both of them, or all of them.
