Apart from being free, the differences seem to be: - Comic Code is more heavily serifed - Comic Mono is "semi-serif" (a balanced blend between serif mono fonts & the sans-serif Comic Sans). Not sure why they both didn't go full sans-serif: I generally prefer serif code fonts but of these two I prefer the less seriffed variation, and Comic Sans literally has Sans in the name. - Comic Code is more legible (for me) - the widths & kerning seem to leave clearer letter separation with equivalent character spacing. - Comic Mono has nicer kerning (to my eye) - while legibility is a problem at small font-sizes, at larger font-sizes Comic Mono is more pleasing to read.
