It appears that my opinion is offending quite a few people. I apologize for that, and I'll just shut up now.
I don't think you're offending anyone

It's a good discussion - and raises some relevant points that could be beneficial for divers.
As a hypothetical... assuming the
same instructor, what do you consider the 'value difference' between Fundies and equivalent training in other agencies?
Fundies is longer/more dives than most competitor agency courses at recreational diving levels. Obviously, longer training produces better results and permits a more comprehensive course syllabus. That costs proportionally more. It isn't "like-for-like" with PPB or Deep - it has much wider goals, which take longer to complete...and which you pay for.
Are there equivalents?... sure, of course. Given a minimum of 4 days training and 5 dives... you could complete a decent AN/Tec40 course which'd cover most of the same knowledge and skills - and which a well experienced instructor could easily match in quality and performance benchmark to Fundies. Heck... a good instructor could provide a PPB/Deep combination (6 dives) that could reap the same results.
The difference, as always boils down to the instructor concerned. Value is what you're prepared to pay to attain something. If a course is supplied, or a student's goal is to receive 'a card', then there is very little value. If the focus is on skills, knowledge and competency, then value is much more easily identified.
GUE/Fundies does a good job of re-establishing the focus (of instructors and students) on a performance outcome. Thus people perceive value easily. Other agencies, through mindset or policy, do a terrible job of promoting the concept of a performance outcome. Bad instructors provide 'off-the-shelf', minimum standard, courses and shift perceptions to the goal of receiving a 'card', a 'license' or a 'status'. In doing so, they effectively conceal their lack of teaching/diving ability. Some agencies aren't motivated to correct that...
But...
again... were talking about
instructors​, not courses.
