guys, im looking at wifi 7 routers/mesh alike

2 storeys corner house 28x80
current setup on ax3000 easymesh with ax1800 using RJ45 as backbone.
Issue: One of the bedroom is having issue with drop connection (speedtest is ok but real life usage is a torment)... router is below this room. All other rooms got no issue.

Is ASUS BT8 better or 2 x TPLINK BE805 / BE550 ?
