Citing my source:

In my experience, it's a better format than chords above lyrics as the performer can see the chord pattern (for the whole song) at a glance. It seems quicker to find chords too as you don't have to search for corresponding lyric line. Also, I mostly only need a reminder of either lyric or chords, rarely both together, which again I find far quicker with the columnar format below.
