I think that for many people they want to feel they made the best choice in what they purchased, so when someone says something else is better, they defensively try to shoot it down, so that they can remain feeling good about their decision. Occasionally I find people get surprised when I don’t engage in pointless “well my different (but largely equivalent) thing is actually better” debates. A lot of the “holy” wars are like this, iOS vs Android, Windows vs macOS vs Linux, tabs vs spaces, programming language/framework choices, etc Really, I’m happy for you to use what makes you happy and please let me do the same without it irrationally bugging you, even though it has no effect on you.
