Pros
Pro Clashing characters are easily distinguishable
This font offers very distinct programming characters that help differentiate the following clashing pairs: {} vs. (), "0" vs. "O", and "1" vs. "l".
Pro Easy on user's eyes
Envy Code R is quite narrow (like Anonymous Pro) but at the same time squarish. The letters are easy to read and offer a pleasant reading experience.
Pro Fills out the space well
Envy Code R also fits more into a given width when compared to Source Code Pro.
Pro Bold font is the same width as the regular weight font
The bold version has the same width as the normal version which is useful for syntax highlighting.
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.
Cons
Con No Cyrillic glyphs
There are no Cyrillic glyphs in Envy Code R which may be an issue for Russian users.

Con Lowercase "w" is distracting
The lowercase "w" is a bit distinct looking due to the narrow nature of the font. This could cause a distraction to some users.
Con Zero is not slashed or dotted
This can make it hard to distinguish the letter "O" from the number "0".
