010 Editor is currently the industry standard for hex editing, famous for its "Binary Templates" (scripts that parse a file structure for you). Interestingly, the aesthetic and layout of 010 Editor owe a massive debt to Cygnus. The clean menus, the tabbed interface (introduced in later versions of Cygnus), and the focus on editing large files without lag were all refined by Cygnus first.

While 010 Editor added scripting capabilities that Cygnus lacked, Cygnus remained the preferred tool for those who wanted a "pure" editing experience without the overhead of a complex analysis suite.
