since this is for your private use, why not ignore your IT buddy and get the Ubiquiti for around $400 since this is the most economical solution and sufficient for home or small office usage. anything else is overkill
what's the fully filtered thruput of the Ubquiti, packet inspection and all? or does it not do that AV stuff?
for simplicity and cost, the ASUS appliance is even cheaper. only provides a couple of 10gb ports and those might need snapin hardware.
since my buddy w be the one configuring it, and he doesn't hate all Ubiquiti stuff just this one, minimizing his time is a consideration.
