Support from SW is superior. End of discussion. Fortinet support was lacking in product knowledge and was noting but reading from a script. SW, if the T1 can not answer I get to T2 immediately. Never an issue to get a resolution in minutes, not hours or days.
Our customer base is SMB so I can not speak about a larger customer base or organization. I have customers with 3 end points behind the SW and customers with 200 end points behind the SW. The biggest confusion on selection is the WAN / LAN throughput. Once you understand the limitations and select the correct product I have been happy with the product on a wide range of customers. It is a bit pricey for a small operation but if they are handling sensitive data it is very cost effective.
