Grep the old Usenet groups and mailing lists for endless discussions about Scheme vs Common Lisp if you're interested in the debate. You'll find a lot of informed and relevant arguments.
These kind of questions ("what's the best programming language?") are kind of useless. They're lacking an adjective complement to make sense. Best for what use case?
