When it thinks about tourism, trips as are the first Brazil option or Argentina?

I really love to travel. I have been to many places in the world but not South America yet. I adore tropical places with waving palm trees and golden sand. I would love to visit Brazil. I have seen some quite cheap flights to Salvador. I think I would see some beautiful scenery and frindly local people there. It would be amazing to travel to Rio de Janeiro and go to the top pf Sugar Loaf Mountain.
