First off, no human can compare to the Lord of Asgard, and quite frankly, the reality gem is a whole different animal.
Secondly, the power gem backs the other gems with unlimited power. Meaning it doesn't really have a specific function other than granting unlimited power to the user/gems. Thus, even if the user had no working knowledge of the pg, he would still benefit somewhat from its use, albeit not as much.
To say the power gem offers no assistance to the user is a little ignorant, and considering Thor does have the "will and knowledge" to use them, such a claim is irrelevant, and ultimately incorrect.
