A correctable error (e.g. a typo, as most will still be understood) is better than an uncorrectable error (e.g. a change to a word that may still made sense in the context). Offering to correct a word, rather than silently doing it, will like lead to correct text, rather than text that _appears_ correct faster - I can very quickly scan for a UI prompt suggesting there is a typo, but I might never notice when a word is silently changed for me. I've noticed this on Windows Phone - on WP8, the background colour of the suggested word briefly changes on an automatic correction, so it's easy to notice and double-check it's done the right thing. On WP10, it only gets slightly bolded and only until you hit space. I've had multiple emails where I've not noticed a erroneous correction until I'm later re-reading it for whatever reason.
