Sunrises and sunsets can be similar, depending on the clouds etc, but I do prefer the sunrises as there is a kind of suspense when you go out early and it is dark and you never know what the sunrise will bring
with sunsets its light as the sun goes down so you can see the skies and clouds and have some idea what the sunset will be like
If it depends on the clouds, then in my opinion, a sunny morning is the most ideal color shown by the sky. But it turns out, on your images the weather is a little cloudy and that actually makes it an even stronger composition.
In my opinion, in the morning a lot of people are still sleeping, so the image will look pure nature photos without human activities. The rest is very rarely the morning image can be generated.
I do get what your saying and I agree that makes a lot of sense ;)
