hi, anyone have any experience with comparing Deco X20 vs TP-LINK Archer AX73 AX5400?

I want to know about the wifi signal strength since its very important to me to have the best wifi range possible. I didnt plant to buy a second routers / mesh since my house is not that big. but i want to make sure all my CCTV can be connected with my wifi, since they are all about 7-8 Meters apart and 1-2 walls between them. also i’m considering mesh routers since i love how simple they look.

also suggestions for different routers are welcome. Thank youuu
