I've installed and used:
Luxul
Cisco
Ubiquiti
Araknis
Netgear
D-Link
Untangle
DD-WRT Firmwares
Tomato Firmwares
I like Ubiquiti's transparency with their integrator/consumer.
It seems to me that the AV industry saw a category that they can add to their product line and are packaging up Luxul, Pakedge as some sort of elite networking product.
But I don't think Luxul and Pakedge are worth their asking price considering companies like Ubiquiti are on the market offering more robust solutions at half the cost.
