Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great for Haskell
Pro Has a heavier appearance than Fira Code or Monoid
Pro Completely free and open source
Freely available via GitHub, therefore can be modified and improved by anyone.
Pro Has many variants such as Italic, Bold Italic, Light, Semibold, etc., etc
Pro Characters readable even at small sizes
The characters in Inconsolata have a slightly "wide" appearance that aids in readability, especially at small font sizes.
Pro Excellent readability
Very clear, distinct characters with decent spacing make Inconsolata very readable.
Pro Efficient scalability
Inconsolata scales well without loss of readability.
Pro Slashed zero characters are distinguishable from capital "O" and "Q" characters
Inconsolata-g screws this up by replacing the slashed zero with a dotted zero. A dotted zero is better than a zero with nothing in it, but worse than a slashed zero.
Pro Open source
It's an open source font, meaning it's freely available.
Pro No visible character breaks
Inconsolata renders lines in TUIs without visible character breaks; apparently unlike Inconsolata-g.
Pro Widely available
Inconsolata is available in the package managers of almost every open source OS.
Cons
Con Lacks !=
Some coding fonts with ligatures, like Fira Code, turn != into ≠, but Hasklig does not. The reason for this is that Hasklig was designed for Haskell code, and so turns /= into ≠ instead.
Con Some Ligatures like -<< don't look that good.
Con Has a heavier appearance than Fira Code or Monoid
Con No support for many editors, including emacs
Unfortunately, not supporting emacs is the number one reason I don't use this font all the time.
Con Very cute but not WYSIWYG
You want to see exactly what you've typed, not have your brain have to do a little dance every time you see one of these artifacts.
Con Arched braces
Too much arched braces, decreases clarity, touching characters almost.
