Colombia probably has the greatest variation and genetic resources of Guanabana.
Commercial varieties from there that are grown in Brazil are the 'Morada' (most recommended), the 'Lisa' (i.e., "smooth", not to be confounded with the Floridian atemoya), and the 'Blanca.' A more recent selection in Colombia, by the ProFrutales company, is the 'Elita.'
A selection in the Philippines is the 'Aguinaldo'.
I have never had plants of any of these.
In many places soursops are simply categorized into three general types, "sour", "sweet", and "fiberless."
