Pros
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).
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.
