Super #17 stomps on account of Ranger #17 being at best comparable in power and nowhere near as fast. Those above SSG tier but below the Hakaishin are at best Multi-Galaxy level in the manga, a tier already reached by S17 Arc Base Goku, and the Super manga lacks anywhere close to the speed feats of even the Toei continuity's Cell Arc characters.
If it was the Super anime, then Ranger #17 stomps on account of being able to go up against guys that are solidly Universe level, not to mention how debilitating Super #17's weakness would be if he gets desperate enough to try and absorb his other self's energy.
