I would want Lydiard if I were a man, and Daniels if I were a woman.
While there are notable exceptions in both directions, men and women have different physiology and gain maximal benefit from different emphases in their training.
Daniels is a tremendous coach of men (and cleaned my clock regularly with his Cortland men), but the fact is that he has not coached men to the same level as he has coached women.
Lydiard did work with some women (of course, not as many were running back in the day), but his workouts drew on NZ athletes who tended to be physically strong through a childhood of a variety of sports. I might actually use Daniels's system with a guy who had not developed strength/joint integrity during his younger years; but if a guy was structurally sound, I bet he'd benefit more from Lydiard.
Men and women have different needs and respond differently to a given training routine. I'm constantly amazed that, in the 21st century, people still think there's "a" way to train males and females alike.
By the way (don't know if someone mentioned it earlier), Lydiard's first book was, I believe, Run to the Top.
