Is Quetext the Best Plagrism checker tool?

A friend told me that most plagiarism detection tools, even the premium versions, are ineffective. So he gave me a better option to try Quetext. Is quetext the best plagiarism checker tool?

Quetext is okay, and while it’s great, it’s also pretty expensive.

They charge monthly fees and limit you to checking 200 pages a month. To make matters worse, their support is practically useless.
Just to add, their contact widget doesn’t even have a way to get in touch.

Its kinda hard to recommend this to someone with such faults.

Quetext is a dependable, secure, and very useful tool for easily confirming original work.
