Definitely the most forced "epic" rivalry of the past 20 years. I don't think the two really particularly had any chemistry, but because they came in at the same time and made it to the top around the same time, WWE thought it made so much sense to have them as the feud of a generation. Despite their seemingly 700 matches against each other, I wouldn't say either make it to the top 5 feuds of either guy. The most memorable matches are the I Quit match for how silly it was, and their Rumble match in 2014 where the crowd was SILENT and then turned on it hard.
