Is there any advantage to using "ppa:mozillateam/firefox-stable" over just using what's available in the repositories for 11.04?

Packages can take a bit of time before reaching repositories, having the ppa enables you to get the newest version earlier. And that is it really.
There is currently no advantage to this as Firefox releases are pushed out to the distribution as quickly as possible after a Firefox release:
In fact, that PPA is being retired.
