Here's a popular question these days: "when can I stop supporting IE 11?" With GA, the answer comes in a couple of clicks; revenue generated sliced by browser version. I don't even see the revenue generated section of Plausible, or really any way to associate any metadata with custom events. GA gives you this functionality without any coding.
If you don't want to use GA, try something like Amplitude, which has a lot more data manipulation options than Plausible.
