I personally use Hack which is a tweaked version of Plex Mono, part of IBM’s Plex typeface. Which is free. I also love using commercial fonts like: Gintronic or Cartograph. I do find Drafting mono for $10.00 very good and very affordable.

Commercial

• Adobe Fonts once was typekit. You need a creative cloud subscription to use.
• Blambot don’t use comic sans use a real comic book font!

There are lots of small type houses out there run by designers. Support them if you can.
