Cisco ASA 5506-x, Juniper SRX320, Fortigate 60E, Sonicwall TZ400

I'm a one man shop needing to choose a firewall to standardize on. I have experience with all of these firewalls except for the Cisco. The most important aspects for me would be:

1. Stable VPN Client
2. Antivirus/Antimalware - ability to run a report and show things that have been caught on what devices
3. Throughput
4. Web Filtering - ease of use, ability to run a report and show what sites have been blocked on what devices
5. Easy to copy a config from a production device to a new out of the box one.
6. Wizards - ability to automatically create NAT policies without needing to hand enter them

Thanks for your input.
