I think the clojure syntax, with those symbols differentiated, is a pretty great choice.

The choice of default meanings is good too, lists/application, indexed sequences and k/v mappings are useful widely used primitive constructs (clojure makes sets (the math meaning, unordered collection, no dupes) with #{} which is handy).

It cleans up the code nicely, having these literals, and now I find non-clojure styles to be a bit annoying to read with the extra noise from contructor function calls.

And when describing data/DSLs using these literals people generally carry the general meanings over, so things can be a bit more intuitive. And in a lot of places just using ('s and ['s in a way that makes it easy to disambiguate them when reading some DSL or literal value also makes for nicer reading of code (just in terms of a bit less mental parsing effort).

I'm the type to not be immediately a fan of extra syntax added to a lisp, but I've been convinced that edn notation is pretty wonderful and I've been converted.
