A proper backlink monitoring tool?

I can't find a proper tool for this, I have tested most:

• 'Monitor Backlinks' (messy crap interface)
• Link Checker Pro - Pretty good UI, but lacks features and is a quite young app.
• tiberius variant (It didn't seem very good either)
• Backlinking.co - Can't even signup as the link is broken.

We're looking for something with good tagging/grouping and a solid clean UI where all details/columns are customizable
Obvious Ahrefs and others do not work for this, and we do not want to show BL that we haven't specifically added for monitoring.

What else is available?
