There are multiple factors: - We've designed these icons according to new design styles like Flat in mind. Thus all the line icons are pretty sleek when it comes to usage compared to Font Awesome. - You can request more icons from us and we'll be happy to add them to the library. We're mostly adding new icons on monthly basis. - We love & powered by Open Source. So all our premium icons are free for all the open source projects. - First ever unique Monochrome style available that will look great for all your landing pages too. - Many more!
