Plagiarism Checker X and Copyscape

[SEO2k]

When I check for article uniqueness on Plagiarism Checker X I get high % of duplicate content but when I check with Copyscape I get none.

As far that I get it, and I might be wrong, the Plagiarism Checker X checks not only the exact match, but also check similar phrases from the all article and combine them.
Should I consider Plagiarism Checker X? or Copyscape is enough?

Copyscape is enough good to use mate

I have been using both of them for quite long time.
Anything in PX over 85% unique passes copyscape.
You can trust both although PX is a 1 time investment.
Hope that helps you.

My suggestion is Copyscape.

Copyscape isn't very good.

It has blind spots.
