During the flashback? sure. After that? It's as true as Garp>WB or WB>Roger.
There's no offscreen magic growth spurt Oda wants to convey to his audience that Roger gets but Garp doesn't, this is the only time we will ever see prime Garp and Roger on screen in depth together, and Oda did everything in his power to not even draw Roger above even by a hair. It's over. He cemented Garp = Roger for his audience.
