ASUS supports their routers for a very long time (5 years or more). I have a preference for their routers. And you can always flash Merlin’s firmware. Some people really like Netgear, I haven’t used theirs in a long time. But you are kind of comparing routers in different classes in terms of WiFi. That TP-link is way more powerful than the other two. The AC68U would be closer to the Netgear, but the AC86U is much more current and probably would be supported longer. The 86U is also now under $200. And comes with a lifetime AiProtection from Trend Micro. Which, some people love and some people hate. But I think Trend Micro also does the security on other brands as well, though I think TP-Link switched to Avira for their HomeCare pro or whatever they call it. I’d recommend an Asus AC86U, personally. I had an AC68U and it served me well for years. Also, if you have a small house/apartment and not too many devices the Gryphon Guardian (I think it’s going for just over $100 right now) is a very secure router, but lacks power user tweaking.
