When comparing Microsoft Consolas vs Input Mono, the Slant community recommends Input Mono for most people. In the question“What are the best programming fonts?” Input Mono is ranked 4th while Microsoft Consolas is ranked 10th. The most important reason people chose Input Mono is:
Input can be configured online with preview: width, weight, line height, and alternate letterforms.

Pros
Pro Differentiation can be easily made between alike characters
There is good overall disambiguation of similar-looking characters in Consolas. For example, there are slashed zeroes, meaning the number "0" (zero) can be differentiated from the letter "O" (Oh).
Pro Available for Windows and OS X
The font is available on machines running Windows Vista, Windows 7, Windows 8, and Windows 8.1, as well as part of Microsoft Office 2007 and Microsoft Visual Studio 2010. Otherwise it can be downloaded from Microsoft's homepage. It can also be set up on OS X machines with instructions on how to do it available here.
Pro Nice appearance
Consolas has a good appearance and character without being too distracting.
Pro Can display a lot of text due to narrow width
Consolas is really narrow compared to most monospace fonts. The more narrow each symbol, the more text you see on the line.
Pro Includes true italics
There are true italics for this font, compared to obliques with most other monospaced fonts.
Pro Includes a large number of unicode ranges
Consolas supports 30+ unicode ranges including Greek, Cyrillic, and Thai for a total of 2735 glyphs.
Pro It reads so smooth
This font reads so smooth that it actually feels annoying to see it being treated as a programming font. For god's sake, don't treat it like a programming font, because this is the best general-use sans-serif font in my opinion. The humanist letterforms and the balanced monospace design are surely a great combination. Not to mention, unlike many other fonts, Consolas is the one to get character shapes "right". The "support bars" design on i and l allows for comfortable text reading unlike the abstract curvy design on some other monospaced fonts. And the r is also done properly, it curves all the way down.
Pro Supports patch that adds Powerline symbols
Consolas can be used with the vim plugin Powerline if the following patch is applied: Patch.
Pro Writing/reading text in LaTeX
When writing and reading text in LaTeX text editor, the content is code and text. Code can be read in other fonts, but reading main text in programming fonts other than Consolas can get you frustrated and irritated.
Pro Highly configurable
Input can be configured online with preview: width, weight, line height, and alternate letterforms.
Pro Available in Mono, Sans, and Serif
There are a couple advantages to using a proportionally spaced font in code: comfort of reading, ease of spotting typos, and better differentiation between different kinds of code with font styles. Fontbureau dedicated an entire page to this topic. Unfortunately, a lot of text editors only support monospaced fonts.
Pro Clear distinctions between similar characters
The font is easy to read, has a clear distinction between similar character types, is very customizable with weight and line height. Free for personal/unpublished usage. You can customize the font how you like it on their site before downloading it to use.
In some fonts, it's difficult to distinguish between similar characters such as i/L/1, or o/zero, or m/rn. This font does an incredible job at making all of these examples clearly identifiable.
Pro Clear on low resolution and retina display
The code stays clear on low resolution and retina display with the same font option.
Pro Large, obvious punctuation
Pro Light, Extra-Light, Thin weights
The designer advises using a lighter weight for light-on-dark color schemes.
Pro Serif font is remarkably readable
Pro Condensed and Compressed Thin saves a lot of space
When using the condensed or compressed version with the thin typeface, you gain a lot of screen space and it's still extremely readable for all day coding.
Cons
Con Not free
Consolas costs 129€ for personal use, but you can get it for free (as in beer) bundled with some free MS products (example).
Con Font size can't be changed gradually
Letter height is the same for 9 and 10, and for 11 and 12 pt. When switching from 10 to 11 pt, letter height changes abruptly (whereas line height changes gradually). This makes it impossible to choose exact letter height on a standard display. Size can't be set to 10.5 pt, for example.
Con Italic font is very different
The italic font (often used for comments) feels jarringly different to the regular one - especially on the "g" and "f" and "l" (lowercase L) glyphs.
Con Starting from 9pt, "!" is too similar to "|"
Con Not avaiable for Linux
Con Poor legibility with small font-sizes on non-hidpi screens
Consolas in the 9 to 13 pt range is hard on the user's eyes with any monitor that's 1080 p or below.
Con Small 'L' is too similar to digit 1
You can tell the difference when they are close together, but when used apart, it can be a bit hard.
Con Highly aliased with ClearType
Consolas is specifically designed to work with ClearType antialiasing, so it becomes highly aliased when ClearType is not turned on. This can be alleviated to a degree with any basic grayscale anti-aliasing.
As an OpenType relative of Consolas, Inconsolata works well without ClearType (Inconsolata-g being the most popular variant).
Con Closed source
Although font designers need to make money too, open source model is preferred.
Con No ligatures
This can be a pro or con depending on who you ask, but it would be nice to have the option.
Con In VS2017 this font does not work and displayed as "Courier New"
Con Hard to distinguish "8" from "B" at low sizes
This often impacts upon designers working with hexadecimal numbers. Many fonts address this by either changing the x-height for numerals, making "8" more of an hourglass shape, or making the "B" cap smaller. At 10 pt, there's less than three pixels of a difference (anti-aliased).
Con Gets the job done, but not rounded enough to be pleasant/easy on the eyes
Con Bold 5 and 6 are too similar
Con Decimal digits can blend together in Mono variant
A lot of decimal digits have a similar form, 2's can sometimes look like 8's and so forth, which makes long strings of digits hard to read. I find other fonts like Consolas's digits more legible even at smaller sizes.
In the proportional variants this is less a problem.
Con Easy to confuse lowercase "i" with "1" if you're not used to it
The dot is so close to the body that they fuse, and with the serif on top it looks like the cap of the letter "1". When you put them side by side it's easy to see which one is which, but if you see a code that reads "a+=i" you're going to read that it increments a by 1.
Con The tilde is indistinguishable from a dash
Tilde is basically indistinguishable from a dash, unless you blow the size up huge. The curves in the tilde are too shallow.
