This question is of course settled. However, it has more than one aspect and I am pretty sure there are also a lot of rather amateur people chiming in here ... I am an EE, but in power electronics and not an RF engineer so I am a little bit hesitant to comment too much on it, but my understanding is that it mostly breaks down to two aspects: 1) noise interferes more with amplitude 2) the fidelity of the modulating signal in FM is higher (more bandwidth)
