are you not getting unreliable latency due to the local network
connection between your gpios and pd processes and triggers?
When I used this method previously, timings between gpio reading and pd
receiving the udp packages varied between 5 to 15ms.

This way there is no limitation on PureData side about how to handle GPIO, and this way makes possible management through other softwares or from another computer. It’s very easy and stable, and there are many examples about how to use sockets with python.
