I've used Iosevka for several years since first reading about it on HN, and it quickly became my default font for terminal and graphical code editors. I've tried a few alternatives since, but nothing "clicks" for me in the same way. The main selling point in my case was slightly narrower characters, allowing more per line, while retaining legibility.<p>I assume font preference is a highly personal thing, so I won't wax poetic about Iosevka and try to sell anybody on it. I will, however, say this: if you haven't tried experimenting with other fonts, you really should spend a couple of hours sometime checking them out. You might find one you really appreciate!
