This. The paper I want to cite, I actually make an effort to go to its author's website and grab bib from there. That's the only definitive source of how the author wants to be cited. Grabbing bib from automated tools has created bib hell that we rely upon Google Scholar to clean up via fuzzy matching which screws up things quite often.

That works if it's the author itself, and the author has at least a passing familiarity with BibTeX. Much of the bibtex that you can download from journal cites is itself pretty botched up.
