To understand why oneauto2017 better holds water, you have to look at the evolution of Chinese Android head units.
The consensus among installers is that post-2019 OneAuto updates inject unnecessary "safety checks" and "handshake delays" into the system. For example, a 2018 unit with a 2019 OneAuto update might take 8 seconds to display the reverse camera. The oneauto2017 version does it in 1.5 seconds.
A major complaint against 2020+ OneAuto firmware is the aggressive "deep sleep" feature. To prevent battery drain, modern versions cut CANbus communication 10 minutes after ignition off. The result? When you start your car the next morning, the head unit boots cold (45+ seconds). The oneauto2017 firmware keeps the CANbus transceiver in a dormant but ready state, allowing "instant-on" (under 3 seconds) for vehicles with a proper ACC wire.
