That was the worst out of the 3 matches against taker IMO... The Hell in a Cell one was the best one I'd say, the one at Wrestlemania 30 was better than the SummerSlam one because of the streak being broken. I gotta say I really liked the match at Wrestlamania 31 against Roman, mostly because of the ending with Seth cashing, but the match as a whole was decent. As for the very best Brock match since he came back in 2012; I gotta say I really loved the Cena squash at SummerSlam 2014, because it was never done before that someone would literally bury Cena the way Brock did. But maybe it was not his best performance as a match...I'd have to go with
@Solidus probably the triple threat against Seth and Cena or more recently the one against AJ Styles.
