Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Excellent readability
Line thickness, shape, and spacing help you to recognize characters and words correctly the first time through, without your eyes having to skip back and re-read.
Pro Pleasant aesthetics
The font has a rounded, smooth aesthetic that is particularly appealing.
Pro Easily distinguishable characters
There are dotted zeroes in Ubuntu Mono so to distinguish from the letter "O" (Oh), while the lowercase letter "l" (ell) is very different from the number "1" (one).
Pro Legible even at small sizes
The fonts retain legibility and under subpixel rendering at small sizes.
Pro Many languages
1,200 glyphs, 200-250 languages (native languages of 3 billion people).
Pro Open source font
SIL Open Font License.
Pro Well designed
6x13 fixed is the apex of bitmap fonts. It has a nice, defined character set and great proportions for quantity of text onscreen, making for excellent readability. It is aesthetically pleasing for a bitmap font and has been deservedly termed 'classic'.
Pro Legible at small sizes
At a small text size, each character has a limited resolution. A character size of 6x13 pixels means only 78 pixels per character. Modern fonts are designed to be scalable and are less legible at these small sizes. Using bitmap fonts increases legibility by eliminating scaling and sub-pixel aliasing artifacts. Some scalable fonts include "ppems" embedded bitmaps for this reason.
Pro Available on every X server
6x13 is the classic fixed monospace bitmap font that is expected to be available on every X server. It is part of the misc-fixed family. These fonts were handcrafted for readability in a terminal.
Pro Widely available
It is distributed alongside the X Window System.
Cons
Con Lowercase "i" (eye) is tailed, and too similar to lowercase "l" (ell)
Same with Hack and Red Hat Mono.
Con Many characters seem imbalanced
Some of the characters don't feel like they match well which can be distracting.
Con The font is too small
Ubuntu's 13pt looks like 10pt of another font.
Con Lowercase "m" is weird and stands out
The lowercase "m" in Ubuntu Mono really stands out because of its unusual shape, which disrupts the user's attention when reading.
Con Dotted zero characters less distinguishable
Dotted zero characters are much less distinguishable than those that are slashed.
Con No support for combined unicode characters
For example, x̄ is rendered as x ̄.
Con Doesn't have a slashed zero
The absence of non-slashed zeroes makes it harder to distinguish "0" from the letter "O".
Con Extremely small on high-DPI screens
While it is crafted for a screen where the pixels are visible, bitmap fonts do not work well on high-DPI screens as they do not scale too well.
