However, notice that they only claim that Lilypond's default output tends to be better than other software's. It's not always as good as a good manual engraving. You have to tweak it to get it right.
Just today I printed this Tchaikovsky piece. Compare the manual engraving with a Lilypond output here (1st and 3rd links):
In particular, look at the the Poco meno mosso section at pages 6 and 5, respectively. While the original has 2 bars in one line, the Lilypond version has 3. Not only the notes look too small, but the 8va in the second bar is almost unreadable.

But, alas, I cannot play it anyway.
