setuptools
The most widely used traditional build backend and packaging tool in the Python ecosystem. It is present in nearly every Python environment by default, requires no additional installation, and has long served as the underlying dependency of the setup.py system.

uv-build is a PEP 517 build backend provided by uv, used to replace traditional build backends such as setuptools, hatchling, and flit, and is responsible for building source packages into wheels.
Opponents believe that the build backend is not the main source of performance bottlenecks, and that for the vast majority of Python packages build time is mainly spent compiling C extensions or running tests rather than on the packaging logic itself, so the speed improvement brought by replacing setuptools with uv-build may be negligible in actual projects.
The net benefit brought by replacing setuptools with uv-build is almost negligible in projects that include extension compilation; only in pure Python scenarios with frequent rebuilds might the speed difference be perceptible.
