There are a number of things were Chrome is worse, actually.

I do wish Web USB would be more supported in Firefox/safari etc. not sure why Chrome is so far in front there.

This is considered insecure. Firefox devs think that prompting the user for permission does not inform the user enough about the risk. See https://bugzilla.mozilla.org/show_bug.cgi?id=674718.

That bug is talking about a custom USB API for Firefox OS.

> Closing as WONTFIX since FxOS is no more

The Web USB API didn't even exist when that bug was first created.

I was thinking more in terms of replacing traditional desktop apps that work with USB like sensors, single-board comp dev, and hardware diagnostic tools (protocol analyzers etc) it’s nice to be able to quickly update a webapp and have native access to usb as needed.
