From my personal experience, I would recommend Brazil. Brazil is a huge country with many options. South of Brazil is considered to be much richer than North/Northeast. Most of the GDP is made in South such as Sao Paulo, Rio de Janeiro. Sao Paulo and Florianópolis are considered to be more like European. Therefore, South of Brazil has a better quality of life because of high income and population density. Foods are always fresh because North of Brazil always have sunshine and of course there is also the Amazon too. Always have plenty different type of fruits, vegetables and lots of meat, especially beef. You also find plenty of beaches since the costal is thousands of kilometres. People are generally very friendly, kind and always open for conversation with anybody. South of Brazil is more expensive than North however if you are coming from places such as US, CANADA, EU etc.. even South of Brazil will be very cheap for you. I never experienced any danger in Brazil however there are places where you need to pay more attention to your things. Rio is typically one of these places and of course the favelas. But of course you do not want to go to favelas because there is not hing for you there. So it is obvious. I also would like to mention that people tend to have a very different mentality over there than in western countries. People take care each other don't overlook on each other. Relationships are very important. Money is not everything and people do not do things just for money. Most important is family!!! They love enjoy life, have deep conversations, good food and football on the beach.
