Pros
Pro Makes code very easy to read, especially if using the version where zeroes are slashed
Feels very easy to read code, even in a very small px (like 10 or 9). Letters are slightly separated, l (ell) and 1 are different, " (opening and closing quote) is straight and not angled, and the "Zero Slashed" version makes it an excellent font for coding.
Pro Size and spacing are excellent for readability
Very easy to scan through code. Large character size for fonts of the same type size.
Pro Looks neat
Droid Sans Mono looks beautiful. The only disadvantage is that there's no italics or bold.
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
Cons
Con Zero is not slashed or dotted
This can make it hard to distinguish the letter "O" from the number "0".
Con Superceded by Google Noto Sans Mono
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.
