Netgear Armor - views?

Hi

So I'm nearing the end of my second week with Orbi and *mostly* everything has been good. I am having some problems with the connection dropping to Apple devices... iPhone, iPad and AppleTV but otherwise ok. I have read a few posts where users are being advised to turn of Armor protection.

I'm trying to figure out what exactly the benefits of Armor are? If  don't renew/switch it off, I assume the router is still protected by a firewall as with any other router? What do I lose by switching it off?
