Cisco TAC support is very good since they have engineers available 24 hours a day, 365 days a year. Important to mention that you must have the support of the solution enabled to be able to receive a response from TAC and that we can be taken care of. The only drawback may be that they will not be able to see settings of the email provider you use.
Any time I've had to use the support, it has been great! They always will recommend certain options, as well as explain what they do and why they are there. The support always gets back to me the same day, and are always pleasant to deal with. I never hesitate to call.
Cisco was at least better than or equal to the others but within our budget. It provided all of the services of anti-spam, content filtering, anti-virus, DLP, encrypted email service, scalability, and more than the others. Cisco name and reputation were also key in our decision.
I have used Barracuda Email Security in the past and FortiMail is just as effective. The interface is easy to use, and the configuration is straightforward in setting it up to work with Microsoft Exchange. Spam detection is effective, as well as malware/viruses and phishing attempts. Overall it is a great service.
