As you're probably aware, I'm an Essex supporter of decades standing, so declined to comment too much, so as not to antagonise anyone.
It was a very Essex performance, knowing how to win a game from a dire position, and executing it superbly. I think some of the criticism of Durham has been a bit harsh, though.
Let's not forget that after 4 overs of the run chase, Durham hadn't scored but already had two batsmen back in the pavilion, after conceding 50+ 8th and 9th wicket partnerships. Holding your nerve applies to every player, not just someone who made 40-odd when chasing a sub-170 target.
It will hold Durham in good stead if they learn not only from their errors, but also what their opponents did well, when next in a match winning position.
