LispWorks is great for app development because of CAPI and its new iOS and Android runtimes (although you cannot use GUI framework on mobile devices). The IDE is also best in class. Add to that tree shaker and no royalty fee for runtimes. Performance is better than SBCL for “real” applications. Allegro is the only Lisp that can somewhat compete with Java on the GC story. It’s simply the best Lisp you can use in the server. Even better than Clojure in that regard as idiomatic Clojure tends to run quite poorly and doesn’t allow for much low level tuning. LispWorks for shipping binaries to clients. Allegro on the datacenter.
