It depends on your use case. If you need something that speaks TLS, then no. NaCl is a different (simpler) protocol that does not have TLS compatibility as a goal. If you're building a new application then NaCl is probably a good choice. There are some problems you may need to solve yourself, if your application calls for them. For example, NaCl has no notion of a CA hierarchy.
