I’m amazed — the effect of shooting with a flash during the day (in bright sunlight) improves your photos so much!
For example the left photo is without a flash, right is with a flash.
Note that with a flash, there is more contrast, saturated colors, details, and dynamic range in the photos.
It seems the optimal strategy is then to always shoot with a flash.
