I'd love to understand the issues with the AX86-U Pro; what leads to the hardware being considered unbalanced.This recommendation hasn't changed for many months now.
The GT-AX6000, the RT-AX88U Pro, and as a last resort (very unbalanced hardware that is hard to recommend today, even with your current ISP speeds, now), the RT-AX86U Pro.
See which models are available in your area, and wait for a good sale if you can.
Thanks
