There is no objectivly better here though, its entirely subjective.

The fact that the rest of society has moved on is a fairly clear indication that this subjective premise that 2 spaces is in some way better, shows it clearly does not show enough objective benefit to remain in use or it would be common practice in all of society.

edit: a sibling comment has provided links to a study on this, showing there is not statistically significant improvement in reading speeds reinforcing that this formatting is not objectivly better.
