For me, I think they have around the same speed, with the easiest way to see is to play a Vasebreaker level with a Gargantuar, let it break a vase with a normal Zombie. After that, they walk next to each other with little to no difference of speed, because the tiny distance between themselves is pretty much the same, albeit a few millimeters of difference can sometimes be detected.
