> Slow startup

This makes the jvm a bit less suitable for programmes with short lifetimes (like lambdas), depending on how sensitive startup times are in context... But is mostly irrelevant in long-lived applications like services.

> design that inherently favors class-based languages like Java

Clojure abstracts over this so well that it's really a non-issue for a wide array of use cases / applications. When programming in Clojure, you really don't have to think about objects and classes at all, unless you really insist on doing so.

> frequent need to use Java libraries

This would be going against the grain: you will have a much better time by staying within native Clojure. I've worked on commercial/production applications that barely had any java interop, and whatever java interop there was was rarely ever involved in day to day work.

Disclaimer: I also am not a huge fan of the JVM and I really dislike the Java world generally, but it never stood in the way of me getting stuff done with Clojure.
