I'm not a writer, so I'll defer to you on that perspective. As a reader, I love publishers and editors. I've waded into the self-published world more than most, and I don't see myself buying self-published work again in the future without significant (outlier-level) crowd-sourced reviews like Wool or The Martian.
I have noticed that the proportional amount of garbage is lower among published works, and that the resulting breadth of content is much easier to wade through to find quality content.
