Hardworking Typefaces: What are some great web fonts for interfaces?

over 9 years ago from , Founder at LayerVault

The number web fonts available to us is substantial enough that it's becoming difficult to separate the good stuff from the bad.

While I still lean on Helvetica Neue for most work, I do have a number of go-to typefaces that I like to use in interface design.

LayerVault relies heavily on Avenir Next. It's a somewhat boring choice these days, but I'd love to see what gems you folks are excited about.
