It'll be broken down into 3 Categories Strength - Now this could really be debated but not really last time we saw dark sonic (Via fake emeralds) he was able to destroy a robot who was made to perfectly test his strength out and resulted in literally blitzed into shreds. Due to his silent and more Ruthless/aggressive nature, Its safe to say a Dark Super Sonic Via the Real emeralds would easily be stronger than a normal Super Sonic. Dark Sonic takes strength Speed - Super sonic Super Sonic consistently demonstrates faster-than-light (FTL) to immeasurable speed, capable of traversing solar systems in seconds, fighting across multiple time periods simultaneously, and outrunning black hole. But we know how Dark super sonic is basically supposed to be a (weaker/downgrade) of Super Sonic yet was still comparable to even super sonics speed, its safe to say that a real emerald powered dark Sonic would be just as fast if not slightly faster than Super Sonic. Its a Draw Hax/Abilities - we've seen nothing that really shows any abilities that shows what Dark Super Sonic can do, but we can at least compare it wont be anything like super sonics who can use cyber energy and power himself up more, or be invincible (game wise), or use Chaos Control. Super Sonic Takes the Cake.
