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 The zero is not slashed
The zero is not slashed, which causes some problems when scanning source code. This is not an issue when the IDE supports coloring (like all major modern IDE's), but still there are instances where this is not the case. A primary example are T4 templates, where Microsoft has not yet provided coloring support.
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.
