For SC security, the fewer points of attack between me and the source the better.
For other kinds of quality, I have my own tests which are much more relevant to my use cases than whatever the distro maintainers are doing.
I've been a DD and while distros do work to integrate disparate upstreams as well as possible, they rarely reject packages for being fundamentally low quality or make significant quality judgements qua their role as maintainer (only when they're a maintainer because they're also a direct user). Other distributions do even less than Debian.
