I've been using Comic Mono as my primary font for about two years now. I use it for nearly everything; it's my terminal font, and since I spend a large percentage of my time in terminal I see it all the time. It's funny how many strange looks I share my screen with people, but I find it an exceedingly pleasant font to use. I'm even using w3m to view HN, so I'm looking at Comic Mono right now.
I checked out the limited free version of Comic Code and it didn't seem like it was any better than Comic Mono, and $100 for it seemed pretty steep for the pack, particularly since I'm not a huge fan of ligatures.
