Perhaps it has features that Python, Go, Node, and even Perl do not have. The reader is built in the same language as the rest of the compiler which means you can change it: you don't have to fork and compile a new version of a Lisp compiler to parse a completely different syntax or interpret a new kind of grammar. It has amazing error handling in its conditions and restarts system. It has the best OOP system I've ever used: being able to run the game I'm making, change a class definition of an entity and have all the live instances update while the program is running... is quite awesome. It's still one of the best developer-experience languages out there. The tooling is amazing. The fundamental structures underlying Lisp are quite solid. I like the distinction Phil Wadler makes: Lisp was discovered while languages like Python were invented. Everything in Lisp fits well together. Other languages in this vein are Haskell, SML, OCaml, etc. You can spot these languages because all of their features are usually built from the primitives of the language. An invented language forces the inventor to try and remember how a new feature may interact with all of the others... and sometimes it doesn't work out.
