In a nutshell...
If you are looking at "Wetmore's Plan" from Running With the Buffalos, you'll noticed that one of the early season workouts he has the team run is a session of 300s with a 300 jog on grass(you may have to look it up, I'm going from memory at the moment). If you consider they are running at 5000+ feet of altitude, these guys were running about 1500m race effort/pace with a 2x jog recovery. That looks very similar to what Daniels' "repetition" workouts look like... intervals of 30-60 seconds at 1500m race effort with 1-2 minute jog recovery.
This is also very similar to Lydiards hill workouts during his second phase. Though Lydiards hill workouts included more true 'power' development with the bounding, there are short hill sprints involved.
If you look at Brad Hudson's training, he even prescribes a fair amount of short hill sprints (12 seconds) during his second phase.
They all have different methods of developing the same thing... speed, power and an introduction/preperation for event specific work that will come during the next phase.
I believe they all advice to keep the volume of faster work during these phase to something the athlete can manage, error on the side of caution and it's better to run 1-2 seconds too slow than 1-2 seconds too fast and to allow suffecient recovery between repetitions so that the workout does not become a deep anaerobic workout.
The biggest difference you'll see is the amount of time spent during these phases. The Wetmore/Lydiard plan has more time in phase 1 (base) than Daniels. Hudson's plan is closer in line with the Wetmore/Lydiard plan, but I believe he has his base phase divided into two ~6 week segments with the 2nd 6 week segment including the hill sprints.
I think Daniels plan allows for better racing thoughout the season, were as the Wetmore/Lydiard plan allows for greater improvement throughout the season and a better peak. But this is just my experience/opinion, having had athletes follow the guidelines of both approaches in different years.
*I'm sure Daniels and Hudson check out these boards and may be able to give you a better and more detailed comparison of their programs to the "others."
