There is a very slight product difference in any luxury experience. It adds to the experience after all. However this is meaningless in the overall comparison. You don't drink drip coffee anymore because you love the other experience. It's obviously not "gross" because you were drinking it just fine before you were exposed to espresso. Maybe at some point you'll become disillusioned in being a coffee snob and then go back to drip. It happens.
This isn't unique to you or coffee. You could say pretty much exactly the same thing about whatever brands/hobbies I'm into and I'd feel exactly like you do: that my preference was justified by more than pure emotional connection. In reality, our choices as consumers are 90% emotional, which is why advertising works so well after all.
