Is one backlink tool enough?

Sorry dude, you are misguided!
We are using Google Search Console aka Google webmaster and it shows two days old data and accurate data compared to other tools!

They are not misguided. And I am not saying that you are wrong. From your perspective you are right.

Webmasters tool is good and a trusted one too. But it doesn't show all the data that a SEO needed to see so people often go for paid tools.

They may show 2 day old data. But once you dig down with any professional tool you will know where is the difference between them.
