When comparing Sudo vs Hack, the Slant community recommends Hack for most people. In the question“What are the best programming fonts?” Hack is ranked 9th while Sudo is ranked 86th. 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).
Ranked in these QuestionsQuestion Ranking
Pro Four styles available
Sudo has Regular, Italic, Bold, and Bold Italic styles available.
Pro Works well on Windows
Sudo is hand-hinted for good rendering on Windows.
Pro Good legibility
Different character categories are differentiated by height and alignment. Numbers are a line width smaller than capital letters, so there is no need for a dotted or slashed zero.
Pro Based on the tried and tested Bitstream Vera Sans Mono
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.

Pro Libre webfonts are available in svg, eot, ttf, woff, and woff2 formats
Hack is free for unlimited commercial and non-commercial use. The webfonts are hinted (TrueType instruction set) to optimize display on the screen and are built into all commonly used web font formats with each new release. They include the complete release character set and smaller (filesize) basic Latin subset releases. They are available in the build directory of the repository.
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.
Pro Very readable
Pro Source code is released in UFO format
UFO source format is widely supported by all modern font editors if you would like to modify the typeface.
Pro Powerline glyph patch is included
The regular set is patched with Powerline glyphs by default. There is no need to patch the font to use it in Powerline environments.
Con Zero is not slashed or dotted
This makes for difficulty in distinguishing similar looking characters, such as the capital "O".
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".
