I've used the standard Mercator projection so far. I know that there are always tradeoffs between different projection properties but I'd like to know if there is some standard projection that is recommended for Sub-Saharan Africa other than Mercator.
Because you are "near" the equator, the cylindrical projections (like Mercator) work well (not too many distortions). If you want to be perfectly fair in terms of areas, you could use cylindrical equal area or sinusoidal projection. But this would not markedly differ from Mercator.
