Ø  A digital VCO can have a very clean sine wave, but when it is multiplied or FM’ed it aliases and shows its weaknesses.

Would have to be a pretty poor design to create aliases.   Every r.f. transmitter and receiver in the world does it this way nowadays.  Are you sure you don’t mean sidebands, which are created no matter how the sinewave is created ?
