A lot of the features people are listing have been on Android for years (just sayin).

As an android user, I can say that one main advantage iOS has is better app design/optimization. Just the other day I was using the McDonald's app and a little survey window popped up and it looked like it was from 2008, I mean it was UGLY! Mismatched design ideology is actually fairly common in even popular modern apps on Android. With that being said, as someone who likes making apps, android has it's advantages. You can download the tools to make an app and start making Android APK files for free. This means you can make yourself an app and keep it on your phone permanently without paying for a developer account. I remember when I was doing iOS development you were only able to "test drive" the app for free and after like a week or two the app would delete itself.
You forgot to add an "apps" section. As an android user who uses an iPad for college work, I've been very impressed with the note taking/college focused apps devs have made. I still prefer android on my phone but I like having access to facetime/iMessage and apps like notability on my iPad. Gives me access to the best of both worlds.
You are comparing a brand new phone to one that is what, a year or so old? I wouldn't be surprised if the brand new phone felt smoother. There's also the whole thing about the S22U having an unoptimized CPU, which was addressed in the 23 series with the snapdragon for galaxy processors.
