It isn't really a question which is faster. As more people take delivery it will become more obvious and we won't even need to see videos like the one posted above.
I am a former e93 owner and yes - it was a great car no doubt I still miss it many days. But the f82 is so much faster and so much more powerful. Once you have spent time driving both it becomes very obvious.
Both are great cars but when it comes to the performance the f80/82 is still an enormous upgrade.
