Cisco Viptela vs Fortinet SD-WAN

Hi!

If I was comparing Cisco Viptela (IOS XE) to Fortinet SD-WAN:

Which one should I pick and why? If you have recent hands-on experience, it would be greatly appreciated. Are there any cautions I haven't thought of? Which vendor has a better SD-WAN and SASE strategy? Why have you moved away/to Fortinet/Cisco?

I keep hearing Cisco Viptela is expensive, and FortiNet has a stronger security story.

Below is a brief blurb:

Requirements:

• Routing (IPSec, QoS, DPI, FNF, DIA & NAT)
• Security (ZBFW, IPS, URL-F, Malware Protection, Threat Protection)
