What is special about notes vs say Google Keep? I used to use Notes on my iPhone but switched to keep since it's available everywhere (both my 3 Macs and my Gaming PC).
PS: I know there's an icloud web version of notes but Apple's crappy requiring an Apple device only code every few times I use it and the fact that it's written in some kind of non-webby framework so that each non-ASCII character takes 100-2000ms to appear just really turned me off.
Notes has loads more features than Keep. Things like document scanning, instantaneous capture with pencil, better sharing etc. The simple UI makes it seem like they are similar.
(I also use Keep for the same reason as you but it isn't even close in terms of functionality.)
