When comparing Roboto Mono vs Hack, the Slant community recommends Hack for most people. In the question“What are the best programming fonts?” Hack is ranked 9th while Roboto Mono is ranked 22nd. The most important reason people chose Hack is:
The fonts are in the Vera Sans Mono lineage with a significant expansion of the character set (which includes Cyrillic and modern Greek character sets), new glyph shapes and modifications of the original glyph shapes, as well as improvements in metrics and hinting/TT instructions to make it more legible at small text sizes used for source code. The changelog is available [here](https://github.com/chrissimpkins/Hack/blob/master/CHANGELOG.md).

Pro Fixes many readability issues in Vera/DejaVu
The tilde symbol ('~'), comma (',') and semicolon (';') glyphs have been modified to be more readable at small sizes and/or on non-HD displays. In addition, the underscore symbol ('_') has been slightly lifted for alignment with surrounding characters.

Con Not recognized as monospace font.
Windows does not recognize the font as monospaced. Cannot be used as terminal font.
Con Sublime Text doesn't show italic version :(
font face "Roboto Mono" has different widths for italic characters, disabling to prevent text reflow
Con Too similar to DejaVu

Con Sometimes difficult to distinguish lowercase "i" and lowercase "l"
When using a higher resolution monitor and a smaller font size, the lowercase "i" and lowercase "l" are very difficult to distinguish. The space between the dot and the remainder of the letter seems to somehow disappear, thereby making it look like a solid line, similar to the lowercase "l".
