The Era of Orton reign was fun, good storylines and matches with Cena, HBK and Jeff Hardy.
The important thing with Orton, Edge and specially Triple H is that they were trusted world title reigns on the RTWM, that means they are money makers, and the company wasn't afraid of putting a world title feud on their shoulders.
Guys like Swagger, Great Khali, Christian, Jeff Hardy, Sheamus, Alberto Del Rio, Big Show, Dean Ambrose, and Kevin Owens are not on that level, it doesn't matter how many reigns they had if they never were trusted WM storyline reigns.
You can count the memorable title reigns in the past 10 years on 1 hand, they're very rare. His most memorable is the one in 2007. It had good build and he was peaking at the time, but sadly there is always the master to prevent Orton from reaching his full potential :trips
