My intro CS class was in Racket. Probably 99% of people used DrRacket and were fine with it (to be fair that was the you haven't really programmed before class). I had to use it for some of the graphics assignments and it's... fine? If you're going to keep using it, make your life easier and use a proper monospace font (like Consolas). The default (I think Cambria?) doesn't align parentheses and brackets with each other and it makes it hard to read (at least for me).
