When using a text editor or IDE that does not allow the user to adjust the line spacing (aka "leading"), my choice of programming font for the last 1.5 decades has been Lucida Console. It has tighter line spacing than any other monospaced font I've seen, thus displaying more lines of code within a window of a given height. Every time I hear about a new font designed for source code, I try it out, and am consistently disappointed at how far apart the lines are spaced. I haven't tried Hack, but looking at the screen shot it seems no better than other fonts in this regard.

Font designers never seem to consider tight line spacing as a potential selling point, and that makes me sad. :-( In fact, wider line spacing is sometimes touted as an advantage, for readability.
