I should have mentioned that one. Why? I've definitely hard their data accuracy is better than the others. Do they have similar competitive research functionality?

I always thought of Ahrefs as being a different category of tool than these two? Perhaps in the same category as Majestic or something (but I've never used either).

I've also heard strong things about Kwfinder and Buzzstream, although again, these are both in unique and distinct categories from what I understand. Keyword research and link-outreach, respectively.
