There's a certain refinement to Cena's work whereas Roman works a little more stiff. Not saying one is objectively better than the other, but for someone like Taker, Cena's style would meld better.
Also, as you said, the street fight gimmick was thrown in last minute, so there was zero time to prepare a good match. I'm not saying it needs to be Steamboat/Savage level of rehearsed, but I honestly saw WM33 as a preparation for the end, rather than the definitive end. Make the definitive end against Cena, and put the thrusters on Cena for a showdown with Reigns at Summerslam.
