Maul (Rebels) vs. Darth Maul (SoD)
A new quote has surfaced regarding Maul and his power level as of Star Wars Rebels. We know of one quote that says Maul is "more powerful than ever" that comes from a SW.com article, but another quote claims Maul has gained new abilities throughout his life, which would obviously include his time in solitude up until Rebels.
The quote: "Darth Maul returned to the Star Wars universe in a big way this year. It seems like there’s just no calling it quits for the vengeful Sith Lord. Although he has grown older and gained new abilities throughout his life, Darth Maul still builds on the teachings he received from Darth Sidious. Now, he’s trying to pass them on to Ezra Bridger."

Seeing that that's now two SW.com articles claiming and / or implying an increase in power, what does this mean? Who would win in a battle to the death? Maul as of Rebels, or Darth Maul as of Son of Dathomir?
