OK, I was reading and posting from a phone screen while commuting. From a laptop screen and based on your screenshots, I agree. The Hack-i looks like a tiny backslash, quite disrupting the flow of reading. The Hack-a at your rendering looks like a small 8 when viewed from a distance, unlike the Dejavu-a.
Next time you post screenshots, make sure that they will fit in a browser window with menu bar on a 1366x768 sceen, though. The browser was messing them up by an additional scaling.
