With all competent coaches, the similarities are more striking than the differences. See for example Rippetoe and Dan John in this
recent conversation. One of the questions from the forums was, Dan John recommends front squats for beginners, Rip back squats, which is right? Basically they just laughed.
I think I am fair in guessing that behind their laughter was the thought that whether you low-bar, high-bar, back or front or barbell or sumo or dumbbell or kettlebell or kegs of water squat is much, much less important than that you just squat, and progress in it.
For my part, virtually everything good and useful I do in the sessions I give is due to guys like Dan John, Rip and Markos. Or Ian Martin, my RMIT teacher. Markos taught me a lot, expressing things clearly and simply: "in every session, do a deep knee-bend, pick something heavy off the floor and put something heavy overhead; in every session, do more than you did before, more weight, or more reps, or more sets."
This is pretty much what these other guys say, too. There are other well-known guys who say different things, like Lyle McDonald. But Lyle didn't believe it when Rip said he had a kid do a 300lb squat in a few months of training, which shows he never coached anyone to do that. Results count.
The good I count to the credit of those guys, any of the fckups I have are pretty much my own fault
