The stupid thing is, fingerprint unlock inside the screen is a long solved tech. The touch sensors on a modern Samsung or Oppo or Xiaomi are literally instant. Why put it on a button on the side? Just to be different? Or is that a patent thing?
Usually they require a very specific state of the fingers, not too clean (don't work after washing and drying hands usually) and not too dirty, not too damaged, not too oily etc. Winter zero degree weather causing invisible condensation or wetness on a screen? Nope. Rain or drizzle? Nada. Also Samsung specifically on their S-line has some obvious software glitches I've confirmed on my phone. For example - in normal conditions, inside apartment, with reasonably clean hands, try to unlock and fail 5 times in a row, input password, then immediately lock the phone and try scanner once again and it will work realiably. It seems that having phone initially in "sleep/hibernation" causes its scaner brains to freeze and glitch, and only fully operational OS causes it to start working properly.
I can totally see why Apple would opt for a better user experience, even if it's not as hyped or flashy on a shop display.
I don't think you've used one in the last 10 years based on your comment.

Literally never had any of these problems and I unlock my phone 50+ times a day in all conditions. Again, try a modern phone and come back.
The oldest phones with underdisplay scanners are from 2018, so 8 years ago max, just saying :) .
My current Oneplus is 3 years old and my current Samsung is also 3 years old. That's not that old by my standards. Maybe something magically improved specifically in the last two years, but I will believe it when I see it. I remember EXACTLY the same phrases in 2020 with new Samsung flagship and newest scanner tech. Then there were EXACTLY the same claims next year in 2021, with yet another Samsung flagship. And fast forward to 2023 and the scanners were still subpar. I don't know, we'll see if they will every improve to the level of standalone scanners.
