- in Gambit History works on lines not S-Expressions like in LIPS

- With LIPS you don't need any new syntax to integrate with JavaScript you just use JavaScript directly (let ((msg "hello") (console.log msg)) SIX syntax doesn't look like Scheme.

- Help popup documentation, with LIPS you have documentation directly in the REPL (when you hover over the symbol) and you can access docstring as strings and assign them to values.

- You can create new syntax similar to scheme vectors and make representation the same as code

- You can manipulate almost everything in the language like environments that you can modify

- LIPS show stack trace not one line which gives an error that makes it easier to find where the error happens.

- The Bookmarks allow to run the REPL on every page even PDF files with R7RS spec.

- You can actually run the code that uses quotes (’ The apostrophe symbol) from the spec if you use syntax extension to add new syntax.
