Africa is indeed the best. My go-to strategy is to start Asia, put my first satellite over the US or Russia (depending on who needs the panic reduction more) and then rush Africa the following month. I ignore South America entirely, working on getting North America covered while keeping panic low in nations with 100+ funding.
