Luke and Vader not trying to kill each other doesn't change the fact that they were intended to be equals(and that was before Luke tapped into the dark side.)
Intended is a strong word. Lucas disagrees with that being his intention (ROTJ Audio commentary). I guess his words are not canon to Disney But just pointing out Intention is the wrong word there given Lucas is the one that made those films, not Disney.
Also equally strong with the Force doesnt necessarily mean they have the same mastery over TK. And we know how strict these source books are on technicalities.
And personally I still think ROTS Anakin is > Vader in Sabers.
