When comparing Anka/Coder vs Hack, the Slant community recommends Hack for most people. In the question“What are the best programming fonts?” Hack is ranked 16th while Anka/Coder is ranked 39th. The most important reason people chose Hack is:
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](https://github.com/chrissimpkins/Hack/tree/master/build) of the repository.

Condensed and, even to a greater extent, narrow versions allow for compact lines without sacrificing readability.
Pro Zero distinguishable thanks to protruding slash
The zero really stands out and looks quite different from zeroes in most other fonts. The addition of the slash means you'll never have to second guess if that character is actually an "O" or if it is a "0".
Pro Practical yet stylish
Anka/Coder has just the right balance between style and readability.
Pro Open source
Because it's open source, Anka/Coder is freely available to anyone.
Pro Libre webfonts are available in svg, eot, ttf, woff, and woff2 formats

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.
The changelog is available here.
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.
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 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 Some characters aren't distinguishable from others
This is especially the case with the colon, which is barely distinguishable from the semi-colon.
Con Not quite as charming at sizes of 10 and 11 pt
There are some hinting issues at these sizes: upper curves are bent sharper while the lower look is squashed to the baseline. Also, the dot of "i" appears merged with the stick at 11 pts. At 9 pts, the font looks good again (nice for watches, compiler output, etc).
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".
