As someone who has read up on Scott, and after my studies are done, will read more up on John, I would ay the approach is different but similar.
Similar because they both apply aspects of high volume to their training. But different as Scott has always considered himself focused on the “art” of bodybuilding s opposed to the science. More the philosophy then the supposed letter of the law.
It’s hard to explain in a way that’s relateable for most. But once you go through and experience the workouts you have a better idea what he’s talking about.
Reading Vern Gambetta, JC Santana, and Ian King helps a lot.
Scott advocates increasing intensity by explosive movement, speed, velocity, and believe that is equal to increaing weight.
Also very big on increasing range of motion and/or speed of movement before increasing weight.
He actually has truly innovative and good ideas and a few more . . unique ones.
I would say principle wise he and John are similar in certain ways. But as far as method goe, they would be conidered on opposite sides of the spectrum.
Scott does use body specialization routines but only as he deems them useful, but he is more likely to do full body routines majority of the time.
Just to give an easier comparison, this would be “Abel” style delt specialization routine:
1)SA KB Snatch 5-6x5-8
2A) Seated DB Press 3-4x6-15rep
2B) Low to high cable chops 3-4x6-15rep
3A) Another form of shoulder press 3-4x6-15rep
3B) Kettlebell Swings 3-4x6-15rep
4A) Some form of shrugs 3-4x6-15rep
4B) rotational movement 3-4x6-15rep
Now thi is not anAbel routine, but it gives you a rough idea. He wants to tax the muscle from all angles. He will add in other movements as both a form of active rest and to get the most “metabolic effect.”
Where as John will occaisionally use the higher rep schemes. Scott will usually cut it off at 20 reps and either increase intensity by focusing on speed, ROM, combining different exercises, etc.
John seems to push for muscle failure in certain scenarios, where Scott would prefer “metabolic failure” so to speak, where you are gasping for air, I mean major oxygen debt.
I’ve always felt Scott was misunderstood in his approach. And once you read his stuff, granted doing it more than a couple times helps, you find he’s not that far out there. He just has a different approach to the principles of exercise.
Writing wise, I have to say John does come off more approachable, and easier to grasp concept wise. Which is proably why his methods are more accepted.
Just my view.
Apology in advance for any spelling/grammar errors. I’m rush typing
