I imagine you'll be better off with the flexibility and ease of nested vectors unless you have very specific performance needs (e.g. you need to pass the arrays frequently to third-party libraries that accept Java arrays, or for performance reasons you want to mutate them in place using amap etc.).
Even the latter need can now be satisfied with Clojure vectors and transients. Once Rich's par branch is merged into the master branch you''ll have access to very efficient forkjoin-enabled parallel operations (pvmap) on Clojure vectors. That's reason enough to use vectors, imo. If you want this now you can compile the current par branch yourself. It's on github.
