It's kind of awesome to see an all out Vision fight. I feel like he's always been nerfed or has held back most of the time. Now he went full Superman.
Everyone in the MCU has to fight themselves at one point or another
Iron Man vs Iron Monger
Cap vs Red Skull
Cap vs Bucky
Thor vs Loki
Ant Man vs Yellow Jacket
Black Panther vs Kilmonger Black Panther
