Big fan of the speed and simplicity of salt vs puppet. Plus it is multiple useful tools in one for me (configuration management, system provisioning and remote execution)
In my opinion it still lacks more automatic deploy mechanisms. Ansible has some great ideas, but I guess the time to write your deploy scripts is needed. I'm still hoping for a salt package like system. (https://github.com/saltstack-formulas) Where you only use your top.sls and perhaps some custom pillar data, to define how packages interact or where packages are needed.
Define wordpress running on 2 appservers + 1 database node + 1 loadbalancer with ssl termination and export db and pipe it through gpg via this pillar key. etc. pp
