A bit late to the game, but here is my way for this.
For a one-off thing, I use the already-mentioned excellent ncdu, which
provides vi-style navigation and even offers interactive deletion.

du is a viable option for quick use on smaller lists. But when it comes down
to actual comparable lists to be stored and archived, I like to use tree. In
particular, I use it to store lists of content of my external harddisks, so
I can find out what I stored where without having to turn the disks on,
including used disk space.

For that purpose, I use two different outputs. One paints the tree as such
using ascii art, showing the size next to the indented name:
tree -ax -n --du -h --dirsfirst

The other one is a tabular format that is easier to look at in long lists,
because it aligns size and date and prints the whole path, which also makes
it easier to diff:
tree -afx -DFins --dirsfirst --du --timefmt "%F %T"
