It’s no opinion, it’s science. The benefits of VO2 max workouts are well know. That being said it’s obviously just one element of a training regimen. The other zones have their places as well. Volume and philosophy ultimately being the deciding factors on zone distribution. 
Why would it change my opinion? You picked mid volume plans while it seems that should have picked low volume. Especially as the low volume plan exactly match what you have described as appropriate intensity!
Anyway, who are those coaches you were referring to and how do they add intensity? Perhaps it’s off value. Or is this thread now just about trashing the TR plans? Guess that won’t bring us a step further also it won’t benefit anyone.
If it’s just about trashing, here are two memes for you. Not saying it applies to you.
