I would also add that musl is less configurable than uClibc. This might
be seen as a drawback (you have less possibilities of fine-tuning the
configuration) but also has a lot of advantages (it's easier for the
maintainers to test the code base, it's easier to know what feature set
musl provides, while with uClibc, each configuration provides a
different feature set, which can be a nightmare for build systems).

Another important thing is that the musl community is much more active
than the uClibc one. uClibc hasn't seen a stable release since a looong
time, and despite several calls on the mailing list since several months
to do a release, nothing is happening.
