Right... However, from what I have read in various letters and documents, it seems to me that Mozart's attitude was more often one of competition over opportunities to gain vital space (i.e., work) held by others, when it was very difficult for him to obtain any (because they were few, but perhaps also because he was too provincial to be a skilled courtier), rather than superiority toward his colleagues as musicians.
In particular, I have always been struck by the fact that Mozart never enjoyed the patronage of court protectors (despite having frequented many) like almost all of his colleagues (Salieri, for example, was "protected" by Gassmann); and I imagine that this might explain several things about certain attitudes of his toward some colleagues (especially a sort of "exclusion complex"). Perhaps because, in his dizzying wandering from child prodigy following his father, he knew well how contemptuous the aristocracy could be toward musicians, even if good manners were maintained; and he could not feel sympathy, with the irreverent spontaneity acquired especially from his mother, for those colleagues who, in those same environments, had known how to bow enough to establish themselves permanently. My theory, obviously.
Salieri. From the documents I have read, it seems that the relationships with the master of Legnago (and with his friend Cavalieri) were of respectful cordiality; nor does it appear that Mozart ever despised Salieri's work, even if the musicality of the two was very different: Salieri, among other things, was primarily dedicated to more or less "serious" theater, in the style of Gluck; therefore, perhaps, there were not many occasions for direct comparison... For example: Salieri wrote only two concertos, and quite ugly ones at that, for piano and orchestra; Mozart, on the other hand, had practically no rivals in the genre; but what Salieri expressed in opera seria was much greater than what Mozart achieved; in general, Salieri's attention to instrumental music is concentrated in a few significant examples, while in Mozart it is monumental; Salieri succeeded in being the best teacher of all time (Beethoven, Schubert, Meyerbeer, Liszt were his pupils), while Mozart derived little satisfaction from teaching... Salieri's sacred music is abundant but truly of little effect (at least for our modern taste), however sincerely felt; whereas Mozart produced several spine-tingling works (from the Ave Verum to a couple of masses, in addition to the Requiem). Salieri was a particularly cultured and refined man ("worldly," as Totò would say), Mozart was undoubtedly on another level... In short, I imagine that their distance in everything (and Salieri's position at court, unreachable for Mozart) never put them in real competition.
