when ios launched it was competing with blackberry, a 55wpm mobile keyboard that I could use without looking.
now it's competing with droid, and most droid devices are lower-end so whatever the experience on flagship devices, it's going to be much worse on average
not what you asked but:
I recently booted an android 10 pixel 1, 5ish years old, 3 OS versions behind current, and keyboard input was starkly better than my normal droid 12 device (both tap keyboard + swipe keyboard)
