Pros
Pro Narrow width saves a lot of space
The compact design of the fonts allows for effective editing in 2-3 windows side-by-side, even on a laptop screen.
Pro Comprehensive Unicode character support
PragmataPro, more so than most fonts (even non-monospace, professional fonts etc.), supports over 10,000 glyphs of the Unicode standard; many of those symbols, letters, and special characters are quite useful in writing and programming (e.g. PragmataPro + Vim's conceal feature makes writing LaTeX pretty beautiful).
Pro Very clear and legible
The font has been hand-hinted with legibility in mind.
Pro Has ligatures
This is useful for those using letters that are joined, such as "æ".
Pro Most complete
The font has the most glyphs of any programming fonts (more than 7.000).
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 Can be expensive
The cost for the bold font is $20 and this can get as high as $225 for the full package.
Con "Bold" is more like heavy/black rather than bold
If you use bold to highlight keywords, you may find that bold version of the font is too bold and disrupts the flow of the text. Bold is heavily used by many IDEs, so you may need to adjust code highlighting settings and use other means of highlighting keywords, or maybe choosing a different color for bolded words.
Con Crowded-looking
Pragmata Pro is quite crowded in appearance, making it rather unattractive.
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.
