I get really good range with mine. I'm currently having issues with the 320hz wifi 7 frequency not being stable with certain clients. Still trying to pin it down.
The GT-BE98 Pro may have an additional 6 Ghz band but what it is really doing is
splitting the channel width into two sub-bands, which can decrease the chance of forming a 320MHz channel. From Dong Knows Tech: "In a 6GHz + 6GHz split, each sub-band’s 600MHz total width is wide enough for
one possibility of a 320MHz channel. As a result, when multiple individual 6GHz broadcasters are in close proximity, only narrower channels (160MHz or 80MHz) are likely possible instead of the desirable 320MHz due to interference." A pure WIFI 7 tri band can have better performance benefits if you have 320Mhz capable devices.
As far as privacy goes, all processing is occurring locally on the BE19000AI as opposed to going through a cloud server that the other Asus routers use and you can run a AdGuard DNS edge server locally, so the BE19000AI would be better from a privacy standpoint.
It really comes down to. Do you need a 10 gig wan port and multiple 2.5 gig lan ports? Do you have multigig internet? Are you interested in Docker/Portainer and running edge servers, smart home servers, NVRs or other network programs?
I have the AI adblocker turned off as it has been problematic with WIFI, the latest firmware was supposed to fix that though. When I did have it on, it would sometimes trigger those annoying ad blocker lockouts on some websites. I also don't use the new QoE function as I have multigig service. So really I'm only using the Docker function which I do like. I have a Home Assistant server, AdGuard DNS, MQTT and Matter server running on it so far.
