Music implies sort of an everything is just an opinion thing so your analogy does not fit.

Think of it like horse drawn wagon vs. a car. There might exist a guy who in his humble opinion thinks the wagon is better so he use it to get places instead of a car but is that guy a reasonable guy? No.

The analogy I mentioned above is more apt because Mongo was indeed at one point in time more of a wagon rather than an unpopular piece of music.
