I'm a die hard PFSense fan however, I so enjoy CLI when configuring devices. It comes from the Cisco background. I just sought out Vyos, an open source community edition of Vyatta, which was purchased by Brocade, and then later sold to AT&T Communications.
The OS has a Juniper feel to it, which I've never used personally, but it's enjoyable. Boot time is fantastic compared to my current PFSense whitebox, I actually have a Sophos UTM 110 coming soon just for VYOS. Thus far, I've done most generic setup: NAT, DHCP with specific options, VLANing, and Port forwarding to my ASA (VPN concentrator).. I however encountered a problem with booting from my primary hard drive, SDA. Grub would not load, unless GRUB was installed on a flash drive, hopefully that doesn't follow over to the Sophos.
As with Cisco IOS, restoring from configurations a breeze: upload through SCP, FTP or TFTP. You can compare commited configuration changes in real time, and revert. each time a configuration is changed, you need to commit the command, it has error correct before configuration is commited as well.
Next I'll be messing with Proxy through Squid.
