Pros
Pro Customisable
The user can adjust letter-spacing, line-height, and choose alternate characters prior to downloading.

Pro Novel use of ligatures to display ascii character combinations as symbols
The common expression '!=' is displayed as '≠', '>=' as '≥' *, while maintaining the fixed width double-space that these characters would normally take, so as to maintain text alignment.
- Many others are supported too - see site for details.
Pro Open source
Monoid is open source meaning it's freely available to anyone.
Pro Sharpness
Pro Larger and easier to read with thin condensed letters
Pro Fine without retina
Probably the only one that is.
Pro Compact
You can fit a lot of text on the screen.
Pro Font proportion is perfect
Width is just right (not too narrow, not too wide). Many other fonts lack this.
Pro Smooth with antialiasing
Smooth at small sizes while still clear.
Pro Readable at small sizes
All characters are easy to recognize at small sizes (comma, period, etc).
Pro Easy to read
This is subjective but this font is very easy to read. The letters are all spaced and sized properly.
Cons
Con Very narrow
Con No bold-italic style
Monoid doesn't offer a style that is both bold and italic.
Con Line doesn't cover text right
When using Neomutt or htop, the line drawn over is too low - the top of the characters cut into the top of the line.
Con "mp" clump together with smaller sizes
E.g. in "The quick brown fox jumps over the lazy dog".
