I don't really think it's innacurate. The only case that most can make against that quote is how Luke couldn't deflect lightning, but people forget that the Emperor himself grew stronger throughout the time era. The commentary with Lucas I'll try and find, I recall Lucas saying something alone these lines: "Well, we tried to show how Luke matured throughout the films. First we see him inexperienced, defeated by Darth Vader. After having that loss he took his training seriously, eventually turning the tables and becoming the strongest Jedi of all time." I might be wrong though, but I do remember something that said Luke was the strongest and it happened during Luke's fight with Vader in the Throne Room.

These things and more."
Vader vs. Yoda I think would have ended up with both killing each other. And who? Yoda or Luke? Sidious was just too strong for either of them

I think you are not giving Yoda the credit he deserves. Yoda destroys Vader.
Yoda could defend himself with little trouble against Sidious' lightning with his lightsaber as he was able to do it with his bare hands where Luke was neither powerful nor experienced enough for it. Both ROTJ Luke and Vader doesn't stand a chance against Yoda 1on1
I don't think Yoda will destroy Vader. Someone who is 80% of the Emperor's power is going to give Yoda a fight. Counting the EU he has TK feats that pretty much rival Yoda, and his combat style is meant to fight people who use acrobats like Yoda. And like I said, the Emperor himself grew stronger throughout the years after ROTS, his Lightning is not the same level of strength as his ROTS self.

Vader wouldn't fare any better than Dooku in AotC. If anything he'd perform worse, considering his hampered mobility won't help against a spinning maniac like our little green friend.
Ok I agree destroy is a strong word. Vader could do well against him with force powers at least defense wise but when the lightsabers are drawn, Yoda would slice him much sooner than ROTJ Luke. He is just too fast for him. Yoda had 900 years of experience too where Luke had just began to understand the force.
But in all honesty Yoda would destroy Vader. Ok so purely regarding TK both are pretty comparable, but Yoda's lightsaber ability is on a level far greater than Vader's. Being able to utterly overwhelm Count Dooku and equal/supersede Darth Sidious as a swordsman demonstrates this disparity.

Indeed he is physically stronger, but his strength wouldn't come to bear with Yoda's blinding speed and acrobatics. As skilled as Vader is, he's not coming particularly close to matching a being who is perhaps the greatest jedi swordsman ever.
