It is simply that I found Racket to be the most pleasant and inviting to use. An all-in-one toolset, with a large and vigorously well documented standard library, and some of the best books on programming there are.

As a sometimes-aspiring language designer who'd already done one esolang before coming to Lisp, the language dev tools that Racket provides were also far too enticing to stay away from.
