If you're looking for good programming fonts, i don't have one over the other to recommend. The real value that black adds is not naturally that it does the form. I no use ot if yoreic. That's if you like ligatures. You don't turn em o, you turn e, you turn o. Hows gong to say? But i went and installed every one of these nard fonts on my new macbook. It took half an hour longer for that little fant book ap was like locked up.
