The Paradise Syndrome is another, not Spock at his best.
Well, he angers his underlings in both episodes. But in the first, he acts rashly, choosing high risk alternatives, and gets people killed. In the second, he acts with premeditation (and during-meditation!), ignores the obvious but fruitless courses of quick action, and succeeds in everything at the cost of no lives. That IMHO is
Spock at his best, and this amounts to a triumph. Even when Kirk and McCoy's inferior choices at the teaser result in considerable jeopardy.
