I bought the Rev 1.1. in November 2022 and am very satisfied. The WiFi AMD Wi-Fi 6E RZ608 (MT7921K) also works perfectly and has a very good 350MBit/s even on the floor above the WiFi access point thanks to the antenna supplied.
The rev. 1.2 has the same Wi-Fi 6E RZ608 (MT7921K) on a newer PCB, but has the same WIFI version a, b, g, n, ac, ax 2.4/5/6 GHz and the same Bluetooth version 5.2.
The rev. 1.3 has a better Wi-Fi chip from Intel® Wi-Fi 6E AX210 but has the same WIFI version a, b, g, n, ac, ax 2.4/5/6 GHz where the 11.ax standard supports 160MHz and up to 2.4 Gbps and the more recent Bluetooth version 5.3 is installed.
The rev. 1.4 has a better Wi-Fi chip than rev 1.1 and rev. 1.2 the Realtek® Wi-Fi 6E RTL8852CE but has the same WIFI version a, b, g, n, ac, ax 2.4/5/6 GHz where the 11.ax standard supports 160MHz and up to 2.4 Gbps and the Bluetooth version 5.2 is built in.

In my opinion, the best current version is rev. 1.3, whereby the differences only concern WiFi and Bluetooth, but who needs more than 1.2 Gbps in WiFi, so that one can use the higher speed, the WiFi access point must also support the 2.4 Gbps and with Bluetooth, the connected devices must also support the Bluetooth standard 5.3 so that one can take advantage of the more stable and more secure version of Bluetooth 5.3.

I got rev. 1.1 3-4 months ago.
