In summary, the experiences tend to show that with lisp you get faster development times, at least as fast execution times, and less variance amongst developers (so there's less risk in using lisp than other programming languages).

See benchmark for programs trying to measure the performance of Lisp systems.
In the "program quality" aspect of things:
- Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken.
- https://github.com/fukamachi/fast-http is 5.5% faster than http-parser, a C library.
That should give a lot of reasons to use CL.
