I have their AX router, Flint and the CPU is actually good on this thing - ARM-A53, Quadcore 64-bit, basically it's a Raspberry PI 3. Most routers come with ARM-A7, an old 32 bit arch, and not all of them are quad-core. When I use OpenVPN, I get over 100 Mb/s with Flint, and <30 Mb/s on ASUS RT-Ax55. I do not think your wireless performance comparison is right, you need 3 antennas to get 1200 Mb/s on AC/Wifi 5, and there are only a couple niche desktop PCIE adapters that can do that. I get 30-40% higher real-world wireless throughput from Flint compared to two high-end AC routers I tested. If you want to really dig into wireless performance, you would have to test real-world throughput. It certainly doesn't have all the bells and whistled of Wifi 6E and 160 Mhz channels.
