I like that Libraesva Email Security just works, and the tech support is great. I also appreciate the method of releasing emails and enabling users to release their own emails. While setting up these gateways isn't easy, their tech support guided me through it, which made it much easier, and I think Libraesva does a good job with guiding the setup.
