Ranked in these QuestionsQuestion Ranking
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 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 Comprehensive Unicode character support
PragmataPro, more so than most fonts (even non-monospace, professional fonts etc.), supports a crazy-wide range 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).
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.
Pragmata Pro is quite crowded in appearance, making it rather unattractive.
