Comparing the same work done between agile and waterfall I can accept your experience of what sounds like an org with unusually effective long term planning.

However the value of agile is in the learning you do along the way that helps you see that the value is only in 10% of the work. So you’re not comparing 100% across two methodologies, you’re comparing 100% effort vs 10% effort (or maybe 20% because nobody is perfect).

Most of the time when I see unhappiness at the agile result it’s because the assessment is done on how well the plan was delivered, as opposed to how much value was created.
