This ios vs android typing thing is all on psychological level.
Using iPhone 8+, Note 8 (re-purchased today) and Redmi 4X.
No difference at all in typing or touch response, the only issue is people buy 80000-100000 set, but then they don't have "budget" to install a good screen protector and then it causes touch response etc like issues. Branded high quality screen protector are must for curved screens.
Note 8 curved screen is a little annoying while typing on edges but i put keyboard at centre and now it does not cover edges and it's all good.
I do a lot of typing on all devices (MS Word, MS Excel) while projecting screen on LED, never felt any difference in typing.
Just sharing my experiences.
