I think you pretty much know everything already. Both are very similar in construction. One difference is that Demeyere Industry 5 is a little thicker and possibility a little more even heating and able to retain more heat. Both are high quality cookware.
Since they are so similar in many ways, I am going to point out some minor differences. M’Cook sidewall comes up more shallow and Industry 5 pan sidewall comes up more steep. In addition, M’ Cook handle has rivets
and Industry 5 handle does not use rivets.
For some people, this is an important difference.
