TidyMacThe short version
DaisyDisk is the better pick if you want to explore your disk visually and decide everything yourself. TidyMac is the better pick if you want each part of System Data explained, labelled Safe or Check first, cleaned to the Trash in one review, and tracked over time with a forecast.
