I agree with Gus, such new wording would be great. Gus, would you like to make a PR?

I'd split the comparison into a second paragraph, and avoid the word "better", instead using something like "but datetime.strptime() also retains both microseconds and timezone data."

Note that such a change of the wording to "similar" rather than "equivalent" will also future-proof this wording from minor future changes to either function.
