Vickery, who is currently recovering from neck surgery, was talking prior to England's Six Nations opener with Wales at Twickenham this Saturday.
The veteran London Wasps star knows first hand the capabilities of the Welsh trio having toured alongside all three when the Lions came so close to a memorable series victory in South Africa last summer.
And the 33-year-old insists the Englishmen who come face-to-face with Jenkins, Rees and Jones this weekend will be facing a huge challenge.
"Gethin, Adam and Reesy are the best front row in the competition, if not the best front row in world rugby," said Vickery.
"Gethin has an engine and a heart the size of a double decker bus.
"Matthew's throwing in and his scrummaging are strong and he will work all day long for you.
"Adam will just keep going. For me, it is not just about the player but about the person. I don't really see anyone better."
