Additive synthesis was a pain to configure. I had to model and estimate the behavior of each harmonic. It was too much effort. Subtractive synthesis didn't work that well for me either. I believe my implementation of the variable cut off lowpass filter had something to do with it. FM Synthesis worked reasonably well without much effort. Implementation was rather straightforward.
