Yeah, the whole "replace a block of text" auto-correct can be a fucking nightmare, but I personaly haven't had bad performance. Maybe I'm just not remembering it... or I'm not thinking of all the uses cases.
On Android the latency of the screen has always bothered me when typing so much I can't notice anything else, but I haven't had a high-end Android device in years where that could be remedied (I was very tempted by the OnePlus 7 but didn't want to fork over the cash just to try).
