Not easy to make a comparison because one is a live performance. And the piano version doesn't give an idea of the result.
About the live performance, I think they play beautifully. Perhaps some occasional inaccuracy? But they play in synchrony.
I also think the length is ok, it the extended version is just to exactly repeat some part, I prefer the live version. I enjoyed this performance, and perhaps it's because I'm not very fond of classical style, and many repetitions make me tired.
