Pros
Pro Very readable
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
Pro Zero distinguishable thanks to protruding slash
The zero really stands out and looks quite different from zeroes in most other fonts. The addition of the slash means you'll never have to second guess if that character is actually an "O" or if it is a "0".
Pro Open source
Because it's open source, Anka/Coder is freely available to anyone.
Pro Practical yet stylish
Anka/Coder has just the right balance between style and readability.
Pro Compact
Condensed and, even to a greater extent, narrow versions allow for compact lines without sacrificing readability.
Cons
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.
Con Liberation fonts are ugly
Con Some characters aren't distinguishable from others
This is especially the case with the colon, which is barely distinguishable from the semi-colon.
Con Not quite as charming at sizes of 10 and 11 pt
There are some hinting issues at these sizes: upper curves are bent sharper while the lower look is squashed to the baseline. Also, the dot of "i" appears merged with the stick at 11 pts. At 9 pts, the font looks good again (nice for watches, compiler output, etc).
