Frankly, this PDF shows that it has been produced with Word. For example:
(a) Full justification without hyphenation;
(b) Chapter 6 ends at page 69, and the next 32 pages have wrong left header; and
(c) Section headers with fake small caps.
Using LaTeX would have resulted in a more beautifully typeset paper.
Your point that you might have spent more time preparing it is subjectively true, obviously, and it seems that in your case Word proved good enough.
