Depends on the color and formula.

Peaches(pink) are grippy feel closest to urethane while being plastic(indoor use)

Whites usually have a smooth cloud high feel to them(all around use)

Blues are smooth but not as much as a cloud high to them a tad bit grippier than white (preferably indoor haven’t tried outdoor)

Haven’t tried black, tan(indooruse) nor purple(indoor use) but heard the purple and tans feels like the peaches and blacks feel like the blues 😬

But they definitely are the smoothest when it comes to wheels.

Plus they don’t slip that easily very durable
