Pros
Pro Tall and legible
Like its parent DejaVu and grandparent Bitstream Vera, this has tall and easily read letters.
Pro Clearly distinguishes clashing characters
Panic Sans has added uniqueness for characters that are easily confused, such as "0" and "O", "l" and "1".
Pro Clarity and appealing to the eye
There is great line spacing and italics in Panic Sans.
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
Cons
Con Line spacing is small
This is a "pro" to me but some folks dislike the smaller space between lines (which is why it raises the underscore, which might otherwise vanish).
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.
