grippers
pros: they are grippy, they wont slide from under you, feel nice and soft to ride
cons: the dehub fairly easily, sometimes even doughnut
sliders
pros: nice and slidy for powerslides and grinds, last a long time
cons: chunk pretty fast, and they slide out from under you alot
i got sliders and i regret the purchase, get vert x wheels, heard nothing but good about those wheels
edit: grippers are traditionaly for park, and sliders for street, but these are not any definent walls, like dylan kasson runs grippers and hes all street
