I run a side business[1] that is lucky to not be dependent on search ads. We started using GA 10-ish years ago because it was free and took almost no effort to set up. But over the years it just got more and more complicated to use, to the point where it got hard to act on the results.
Last year, I switched to Plausible[2] for data protection reasons. The unexpected side effect was that I suddenly understand every single metric in my analytics tool. As a result, I use it a lot more for actual decision-making.
