Pros
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 Pixel-perfect rendering
No blurry characters ever. Every pixel on the screen is used to its full capacity.
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 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 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 Square
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 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.
