The essential choice is simply based on just how much information you want to see and what test equipment (and its spec.) is available. In essence, for narrow bandwidths: FM generator; for wide bandwidths: sweep generator. It's all a question of choosing the right tool for the job - such is the case with many things, not necessarily 'electrical'. The knowledge of 'which tool' comes down to experience (if manufacturer's service data is not available) - like so many things in Life.
