True, it was a good storyline built into both of them too, HBK had always beaten The Undertaker up until those two wrestlemanias and the wrestling was superb, but also had tons of emotion. The second one felt more emotional just because the only thing HBK wanted was to end Undertaker's streak and he gave up everything just for another shot at him and became obsessive.
And as a little kid, Stone Cold vs. The Rock was a dream match for me
