When comparing Terminus vs Hack, the Slant community recommends Hack for most people. In the question“What are the best programming fonts?” Hack is ranked 10th while Terminus is ranked 19th. 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 Looks great even without anti-aliasing
Many fonts look terrible without anti-aliasing. Not Terminus, it looks clear and crisp.
Pro Beautiful crunch pixels
Pro Terminus is not going fat
Many fonts are fatty when they are used relatively large in size but Terminus does not have this issue. And now it works with IDEA.
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 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 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 Very readable
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.
Con Italics are not very appealing
Italicized Terminus TTF doesn't appear as aesthetically pleasing as it was intended.
Con It doesn't look very nice
Con Easy to be confused with different brands of the same or similar name
Like Terminus (Russian production company), Terminus (terminal emulator) or Termius (SSH client).
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".
