Where GrandPerspective is great
It costs nothing, it's been maintained for years, and the treemap is a very honest picture of a disk: big blocks are big files. You can colour by file type or date, filter what gets scanned, and save a scan to compare later.
What Broom adds
A treemap tells you where the space is, but not whether it's safe to remove. Broom's Cleanup screen sorts that for you: caches from 260+ apps, Xcode data, package manager downloads and orphaned build folders are marked safe, while backups and big untouched files sit under Worth a look.
From the same scan you also get Find, duplicates by full file contents, and an Applications screen that removes an app with its leftovers. Everything goes to the Trash, and Activity lets you put it back.
