It does have another big advantage: it's clean. Not having to be compatible with a prior lisp made it possible to have a lot of small things changed. Like the lambda function syntax, or the "def" special form, or the really nice reader syntax for vectors and maps. Both above the hood and below it's based on consistent abstractions. Other lisps would be too, no doubt, but they suffer from having evolved over a very long time. And it grows, including towards what you it's say it's lacking right now. Recently it got the capability to work with mutable data structures (transients), which makes it less functional, but still without giving up the advantages.
