Hello loose-electron,

from the practical point of view (that means: application oriented) I agree with you. However, there are some other aspects.
For example: Understanding the principles connected with terms like "Bode-Diagram, Stability, influence of poles and zeros,...".
And, according to my understanding, this was the reason behind the original question. And in this context, I think it is interesting to investigate the pros and cons of the presented two-opamp configuration. I Like to remind you that a lot of papers were published in the past dealing with exactly this (and some similar) configuration(s).

Beside these arguments, I doubt if you really can find the best combinationof  all relevant parameters within one single chip: high gain, low offset, low noise, high slew rate, high output current capability, high input and low output resistance, ....
Regards

BuddyP -

Not a problem, we get many questions here that can be answered easily opening a book on the basics, or similar.

In this particular question it was pretty globabal in nature, and the structure did not make a lot of sense unless there was a special need in the application.
