Liberation Mono works well with hinting on high-resolution displays.
Pro As of 2023: Second Best screen-modern drop-in replacement for MT Courier New
Metric-compatible with Monotype Courier New, dot 0 (zero), modern non-Kettler lowercase l (ell), 660+ glyphs, OFL-1.1 license
Pro Compact line height
Just like Courier New (the metrics of which this font emulates), its line height isn't too big, which results in more lines on the screen, compared to Consolas and several other more popular fonts.
Pro Has Bold typeface
Cons
Con Small 'l' (ell) is too similar to big 'I' (Eye)
You can tell the difference but need to concentrate on the letters.
See the word "Illegal" as an example.
It would be better if serifs are a little bit wider for the big 'I' (Eye) letter.
Con Smaller than other monospace fonts
Con Small punctuation makes readability difficult
In some programs it's hard to see punctuation marks, especially periods and colons.
Con Smaller then other monospaced fonts
Size 13 of Source Code Pro is slightly larger then size 14 of Anonymous Pro.
Con "0" glitch
The 0 (zero) symbol has a 'dent' on the left.
Con Exaggerated italics
The italicized version of the font is too slanted, meaning that italicized comments in code look really unbalanced.
Con Hard to distinguish [ and {
Braces [] and {} are very similar.
Con Difference between "0" and "O" isn't clear
It can be difficult to tell the difference between the number "0" and the letter "O". However, the Fedora Project has a slightly altered version of Liberation Mono that fixes this with a dotted zero.
