The Web browser is likely the most used piece of software on the average computing device. Yet despite its ubiquity, there is relatively little competition in the browser space. These days even experienced users would be hard pressed to tell the difference between the major offerings. Internet Explorer's new Edge incarnation is slightly different, but Firefox, Chrome, and even Opera are indistinguishable both in appearance and features available.
There may be some small differences, but for the most part a Web browser is a Web browser is a Web browser.
This is especially true when there's no Web browser. The rise of the embedded browser in mobile apps has very nearly eliminated the need for a dedicated one if you spend most of your time in mobile applications. But the disappearance of the browser is not a bad thing. The point after all is not the browser—it's the Web it accesses.
