It depends on your usage. If you use software from the stable releases (not edge), then the testing should already be done for you. And with the rise of Docker/Podman containers, Alpine sees a lot of testing. Because of the simplicity and compactness mentioned in this article, it is very popular in Docker containers. So it has a very wide deployment and tons of testing going into it.
Personally, I value a lean and simple OS enough that I am willing to risk finding these bugs.
Alternatively, you can try Void Linux. It is similar, except that you can choose between a glibc or a musl install. I've not used it yet because it is rolling-release only and that doesn't fit with what I need it for currently.
