Which administrators? In what environments? Remember, the thread started with someone telling us that Mikrotik is a good replacement for Ubiquiti use-cases. Whose EdgeRouters and USGs have easily configurable VPNs with good defaults.
I'd also love to hear about any alternative products which support SFP for WAN and 802.3at PoE with ease of setup and use as Ubiquiti. Or even a SOHO ASUS router.
