A solid argument for Luke Skywalker being the most powerful Force-user of the mythos was once possible. Then Abeloth was introduced which was touted to be a dozen times stronger then Luke Skywalker. This declaration was challenged by some on the basis of superiority of G-canon over C-canon argument but The Ones came in to the picture as well.
You see where this is heading?
Luke Skywalker could be the most powerful Jedi to have ever existed throughout galactic history but a hype more ambitious then this one is subject to scrutiny.

So what? Anakin has never been officially confirmed to be a superior duelist to Colomen Trebor. We can nonetheless draw such reasonable conclusions from analysis of feats and accolades.
Yes, it is possible to establish superiority of a character over another but this is possible on the basis of multiple forms of evidence.

Anakin at full potential is more powerful than Yoda, who is the most powerful Jedi to his point of all time. Nothing in the new canon refutes this. Calling Anakin potentially "one of" the most powerful Jedi of all time does not preclude his being the most powerful, nor do I think that the author of the quote honestly intends to subtly insert that an ancient Force user may have been more powerful than Anakin, and that this is somehow indicative of a new narrative intention on the part of Disney. You're obviously taking a throwaway semantics distinction and trying to run with it, and to call it straw grasping would be quite the understatement.
This is an interesting take on this matter, I admit. However, you are sticking to older sources for information. Latest developments and revisions leave the possibility of your assertion being challenged.
For Yoda:
Yoda was a legendary Jedi Master and stronger than most in his connection with the Force. Small in size but wise and powerful, he trained Jedi for over 800 years, playing integral roles in the Clone Wars, the instruction of Luke Skywalker, and unlocking the path to immortality.

The "one of" point leaves room for flexibility in ranking of Anakin Skywalker on holistic level. He might rank # 1 but he may also rank # 10.

Covered above.
