I'm totally agree with your opinion, i think it will be better if we're not comparing them to each other because they have different characteristic and advantages that differentiated them from one to another.
well, whatever the characteristics, lay people will always ask about the differences in the coins, and of course we can't avoid them. basically many compare bitcoin and eth because they have a different system, but they always ask about the difference of each coin. well, this thing I got happened in the real world.
