Assuming we’re comparing stuff you can buy at a random shop:

- you can blindly hit the keys on a dial pad if you remember their position, on a rotary you probably need to count the clicks

- on a rotary you probably can’t look back at the number you already inputed

- traditional ones won’t have * and #

- no speakerphone feature, which many older people would benefit of

- no mute

- no phone number memory/speed dial

It’s actually fun to think about how much it has changed since the earlier phones, as the land lines are progressively getting obsoleted as well.

I could imagine a modern version of the rotary UI, as a swipe input interface for instance, but it would still be clunky IMO
