There can not be a definite answer as all tools have their own algos

That is right, both of them use different ways to calculate measure such as KD, Volume etc. The same case is for Majestic SEO, Ahrefs, and others tools.

Whenever using SEO tools, use any one tool constantly so that you will not get confused. Each of the seo tools have different algorithms.
