Stanley Thompson. The standout nature of his par 5s is most obvious at Highlands Links, where 6, 7, 15, and 16 are arguably the four best holes on the golf course. But the long holes at Banff and Jasper are excellent too.
Given the framing of the question ("in comparison to his entire body of work"), I wonder whether those responsible for Pebble Beach might be candidates as well, given the quality of 6, 14, and 18.
As for Tillinghast, I have two questions:
(1) Patrick, would you say that the par 5s are the class of the course on any of his top five layouts?
(2) Did Tillinghast build only two or three par 5s more often than most of his contemporaries?
