Is your brain, like, broken or something?
Superman does that better than her. He is a genius on the level of some of the greatest minds on earth. This alone is better than all her plans and strategies.
Diana does have the blessing of Athena's wisdom, goddess of intelligence and warfare, to be good at these things y'know.
And when Superman outplans someone like B13, it tends to be by coming up with something laterally, catching them off guard with an unconventional approach that he personally does. Different from commanding an army's forces or the like, Diana's very good at conventional command.
They have different skills and are better in different areas. Diana, diplomate, strategist, general. Superman, drawing out the best in people, and good at using people good at their tasks (following Batman's plans and etc. etc.). Though, even in the other's areas they're each pretty darn good.
It's sorta the whole Trinity thing, they complement each other and Batman very well, because they approach things in different effective ways, and when you have all three together every base is covered.
What plans and strategies Wonder Woman has made and executed?
There was when she organized the defense of Themyscira and fought off Apokolips. Or the time when he prevented Cronus from stealing the godwave after he'd already defeated multiple pantheons. Or the time she and a small unit of enhanced gorillas fought off an army all empowered by Captain Nazi's formula. Or when she lead an uprising against the Sangtree space empire.
