(at p.104): "Do not place a hairpin before a note is started, nor after a note 
is finished.  A hairpin should start at the first relevant notehead (not 
accidental) and end with the following notehead or at the first rest 
thereafter.  Good practice is to start the hairpin on the left-hand edge of the 
note and to finish it on the right-hand edge of a note[1] ... (If a dynamic 
symbol is present, the hairpin starts later and finishes earlier, so that the 
dynamic centres on the notehead or chord.)[2]"

(parenthetical expressions are Gould's).
[1] The illustrations make clear that the "right-hand edge of a note" implies 
that a "note" includes not just the notehead but also all the whitespace up to 
the left-hand edge of the next note or rest (or, optionally, up to 
just-before-the-barline).
[2] Last time I looked, lilypond had a small problem here: 
https://sourceforge.net/p/testlilyissues/issues/4837/

So, by these criteria, your output #1 is better than output #2 but, without 
seeing what happens after the middle-C, one can't say much about the right-hand 
end of the hairpin.
