Are you going to elaborate on why it’s better or did you just want to be a contrarian?
Is it not enough that trees look better?
IDK why you have to choose one or the other, though.
Why would that be enough when we’re talking keeping a house cool?
I am VERY pro-tree. A lack of trees is why I moved (and why I decided against buying a few homes)… But trees are not a “better idea” for this purpose so it was a useless statement to make

Trees create a cooling effect past shading the area. It’s a combination of shade and evaporative cooling.
Those links discuss cooling outdoor spaces. They don’t compete with awnings for keeping sunlight from warming up your house unless you plant them close enough to do so and come with a ton of downsides (roof damage, leaves clogging gutters, roots breaking pipes and foundation)…not to mention how long it takes a tree to grow tall enough to provide that sort of shade
