I'm not sure if you mean, "Like most Lisps, it's more demo toy than practical tool," or, "Unlike most Lisps, it's more demo toy than practical tool." Depending on whether by "most Lisps" you mean most established Lisps or the numerical majority of Lisp implementations, I could see either reading, and your punctuation doesn't make it clear. There are a lot of zero-user toy Lisps out there.
