I'm not a fan of the notch but accepted it as a means to an end - removal of the home button with Touch ID, which boosted the screen to body ratio without moving the fingerprint reader to the back. My main issue with it has always been software - 16:9 video played back in the native player is either pillar boxed or expanded right to the edges of the display. Pillarboxing negates the larger screen and actually results in a smaller video than on the iPhone 8 Plus, and only 10% taller than on the iPhone 8. Expanding to the edges reveals the whole distracting notch in all its ugliness and cuts off quite a lot of the top and bottom of the frame. My third party video player allow me to set it to automatically expand the video right to the edge of the notch, which looks great and should be built into iOS as the default zoom mode for video playback.
Based on the above, a taller notch is worse in my opinion, regardless of how narrow they have made it. It will make no difference to the pillar boxing, will be more distracting when zoomed, and will result in a smaller video when zoomed using the third party player. When ZTE are putting out things like the Axon 30, with the second generation under screen selfie camera (huge improvement over the Fold 3) and an under screen fingerprint reader, it is starting to feel unnecessary to continue to chop bits out of the screen. I will stay with my XR for another year or 2 and see what happens. It's very unlikely I will go to an Android phone, but I find it very hard to get enthusiastic about the current crop of iPhones when I can't actually see how they would improve my user experience.
