While this doesn't answer your direct question, try taking a good-sized block of text (a couple paragraphs from Project Gutenberg, lorem ipsum text, whatever) and print it side by side, in several different fonts. Compare the feeling you get from the typography itself. I mostly write in MonteCarlo (http://www.bok.net/MonteCarlo/ http://www.bok.net/MonteCarlo/), but programming fonts are a different discussion entirely.
