Link Detox is the best tool to get a quick overview on bad links.
I especially like the quick analysis you can do with LinkReseachTools like competitive analysis. For realising quick wins, I also recommend using the Link Recover Tool that helps you revitalize lost link juice. Link Detox (DTOX), by the way, is the best tool to get a quick overview on bad links causing damage. So in my eyes, LinkReseachTools is the full package for link analysis.
