If you are going to use an example of why something is wrong then it tends to be better if you use an example that’s actually true. My wife works with the Police. It’s her day job. In general access to suspects iPhones drives them nuts. I know for a fact that FaceID hasn’t made the task any easier.
A lot of this comes down to personal preference. For me, At the end of the day, FaceID works better than TouchID. My job is based outside. Here in the UK it rains quite a bit. When my hands are wet, or just a little dirty, TouchID would fail 90% of the time. I found it so useless that I often turned it off. With FaceID it’s such a relief as it actually works for me. I’ve also tried some of the other tech. My old Samsung phone would fail if I had sunglasses, or a hood over my head. Not so FaceID. For me it is better. But surely the notch isn’t just about FaceID. There’s other hardware in the notch.
As for watching video. I really don’t have much time for that. When I do it’s usually when I’m at home. Then I watch it on a big screen. Watching stuff on anything less than iPad Mini size (and that’s pushing it) is just too painful. Occasionally I’ll watch BBC iPlayer content. That has a 14:9 aspect ratio. If you watch that in landscape (as you do) then by default it’s scaled right up to the edge of what is then the top/bottom bezel. If you go full screen then of course some content is obscured by the notch. But doing that is totally pointless as more content is lost over the edge of top/bottom bezel. At the end of the day I just don’t go full screen so the notch isn’t an issue.
How is the notch better. That depends on your definition of “better”. For me it’s better because it makes the phone slightly less tall. When I work I’m moving about a lot. I still like a big screen but anything that can make the phone smaller (even if it’s by a few mm) just makes it more comfortable to carry in my pocket. It’s literally a pain having a phone dig into my side.
Smartphones are full of compromises, both in hardware and software. Of course the notch is a compromise. But personally I prefer it over having a top/bottom bezel however small. That’s why I bought an iPhone with a notch. Nothing’s forcing me or you to buy one.
