The AX3000 from Xiaomi is better, it has a 3 x Gbit Ethernet connection per mesh router and the entire system from Xiaomi is more powerful, it can manage up to 256 devices with 5 cores per router. The X60 from TP-Link manages somewhat less. However, the TP-Link X60 has free Home Care, i.e. antivirus and antimalware integrated directly into the router. This also has advantages, but when it comes to connection options or performance, the AX3000 would be more optimal and, above all, you can get 4 AX3000 routers from Xiaomi for around 260 francs. That is also an advantage.
