Comparing presidents of Argentina and presidents of Brazil

[buritobr]

In bold, my choices
Juan Domingo Perón vs Getúlio Vargas
Argentine Military Dictatorship vs Brazilian Military Dictatorship (the less horrible)
Raúl Alfonsín vs José Sarney
Carlos Menem vs Fernando Collor
Carlos Menem vs Itamar Franco
Carlos Menem vs Fernando Henrique Cardoso
Fernando de la Rúa vs Fernando Henrique Cardoso
Néstor Kirchner vs Lula da Silva
Cristina Kirchner vs Lula da Silva
Cristina Kirchner vs Dilma Rousseff
Mauricio Macri vs Michel Temer
Alberto Fernandez vs Jair Bolsonaro
Javier Milei vs Lula da Silva

There was no time coincidence of presidents in the period between Peron/Vargas and the military dictatorships, so, it was not possible to make the comparisons.
In the other periods, there was a big coincidence of political cycles in the two countries, that's why it's possible to make the comparisons.
Since 2019, after a long period of similar political cycles, the two South American giants started to move to opposite directions.
