Privacy
The difference in data exposure between sharing a @username and sharing a phone number on WhatsApp.
A username keeps whoever receives the contact from learning the real phone number, reducing the trail tied to that number (spam, marketing lists, data cross-referencing). Covers when each option is worth using.

Frequently asked questions
Can someone find my phone number from my username?
No — a username link doesn't reveal the underlying phone number to the person who opens it.
Is it safe to put a username link on a public profile?
Yes, that's the main advantage — it's designed to be shared publicly without exposing your number.
