I routinely read music, very often complex music daily, and I would absolutely have a preference for how the music is notated in Pauferro's example #2 because the quarter note beat is more clearly defined in the given meter. Also note how the tie is used to distinguish the end of beat 2 to the beginning of beat 3. At least the first example also uses a tie.
This way of notating (in example #2) is immensely helpful when sight-reading highly syncopated music whether it's funk, modern classical, or jazz. Just try to sight-read tricky music with no ties or beams (all separately flagged note values without the beat as a "container"). Good luck with that. Look at the way opera vocal parts with librettos are notated, it's a nightmare to read rhythmically.
