I think I've already alluded to this and more importantly, my post was not some treatise on what I consider to be premium. My post was about how the 14 Pro specifically looked better and felt more premium than the 15 Pro.
By way of example, compare a SS Apple Watch with an Aluminum Apple Watch. Which of these are more premium? I think most people would say SS. Because I stated that Titanium looks a lot like Aluminum, I think it's reasonable to conclude that an SS iPhone looks more premium than a Titanium one. Titanium just doesn't feel as nice as SS to me. That's all I'm saying.
