As someone who has worked on package managers quite a bit in the past, and for that examined prior art across package managers, that's because Cargo is doing things very well on almost all fronts. Partially because of their RFC process and partially because they have the luxury of being a "newer" package manager that doesn't have to live with ecosystem baggage going many decades back.

There are/were definitely some weaker spots with Cargo (e.g. private registry support was meh for some time), but if one were tasked to build a package manager and were only allowed to pick a single one to take inspration from, Cargo is definitely the way to go.
