Pros

The transition from daytime to nighttime color modes takes an hour by default and will detect your current timezone, meaning that it will happen in the background at sunset, often without you noticing.
Pro Free & Open Source
It is absolutely free and released under the GPL.
Pro Works in High Sierra and above
Pro Allows ordering disk by size
This way you can find what is taking most of the space.
