Is the range better than a Netgear Nighthawk R7800?

The Asus AX-3000 is absolutely better than the decade old Netgear R7800. The Asus is Wifi 6 and supports 160 Mhz, whilst also having a much more capable processor and way better range. I wouldn't even compare the two. The Netgear was made over 10 years ago, it is terrible as a Wifi router for today.

Are the antennas adjustable (vertical, horizontal, diagonal positioning)?

They are normal wifi antennas. They hindge and rotate.

Can qos be set at an application level so the kids online gaming can be throttled so adults can work at home without slow downs on video conferencing?

I have the asus Rog GT GX11000, with this one you can go into the QOS and put the order in which one you want to give top spot too. It works.

Does this router have to be the main router (dhcp) in order to work or can i have this as a client with aim repeaters to run a aimesh network?

It can be run as a Wifi Access Point with the DHCP disabled. In my case I have a different older generation main router that is also the DHCP server and this one extends that network attached to lan cable.
