ASUS RT-AX55 (Limited White Edition)
Unboxing, Wireless Performance Tests, TM-UniFi Home (800/200Mbps DL/UL)
Wishing all a healthy, happy and prosperous Ox year 2021 !! 
!!
Long story short for the impatient, at RM599 for twin pack limited white edition (~RM300/unit only), this RT-AX55 might well be currently the most value-for-money AX router wifi to consider 
Why I like/recommend the RT-AX55 :
- BMC6755 AX radio
- Newer kernel (currently 4.1.x)
- External antennas (2x2.4G + 2x5G)
- No USB (*note below)
- ASUSWRT --> frequent official firmware update (even beta fw to fix the recent dnspooq vulnerabilities)
- Clean/simple design, light weight, limited white edition
*Note : I personally don't prefer router/wifi with extra I/O burden/packages such as USB, I'll run such USB related functions (e.g storage, sharing, download manager, etc) on proper dedicated NAS.

Run as AP
I use the RT-AX55 as AP mode when needed, usually I'll run/test for at least 3 days especially after each new fw update, just to ensure all my devices are connected ok :
ASUSWRT already released beta fw 9.0.0.4.386.41994 (link HERE) to fix the recent dnspooq vulnerabilities (by updating to current latest dnsmasq v2.84x) :
Update : 28Aug2021:
Finally, current latest stock ASUSWrt firmware now comes with DoT (DNS-over-TLS) support on RT-AX55, nice
