SEMrush vs KWfinder who should i trust?

Written by  on November 3, 2017

Hi guys. I am long term member here but first ever thread :)

Have been successful web developer for many years until now i am getting into IM+Dropshipping and failing badly..
However, i am doing some keyword research for my 3-rd Shopify store, niche based.
I have problem understanding difference between MOZ, SEMrush, KWfinder, for same keyword, they give me drastically different competition metrics.

Any thoughts on this?
