Superman Prime never had a sword and we don’t know enough about him to gauge his power so because of that I’m going with Lucifer but I do have a feeling that Prime does a have chance, it’s just DC didn’t him doing anything special.
Superman Prime dosent really have many feats by he powered up every superman there was while sundipping,he travelled space for like...so long, he recreated krypton,defeated the living sun Solaris and he HAD a sword....it was given to him by The Source, cant remember what it does but it should be very powerful

Pre-Crisis Superman had the Sword of Superman but Superman Prime never had any sword. Prime did do some crazy shit though, he left Earth at the end of the 21st Century and was only seen again in the 700th Century.
From Wiki:
The fear lasted until one day at the turn of the 700th century AD when a haggard and haunted figure descended out of the skies above the planet Earth. Superman Prime, Kal-El of Krypton, the original Superman had returned to his adopted home. He had been places and dimensions that few had even knew of and even fewer understood. He had wrestled with gods and demons. He had overturned hell and fought his way past the gates of Heaven looking for the soul of beloved Lois who due to his immortality he could never join in the afterlife. A haunted figure as removed from humanity as he had ever been his presence still caused a revolution in human society. To many it was the second coming of a legend from the past creating a spiritual revival and even worship of him from some, but he was beyond such social convention at that time.
I gotta say that Supe has not chance. Does he do anything that gives him any other feats. I know those scans are from the JLA one million series which I have but are there any other that he appears or does anything?
Superman Prime (Yes this is the Pre-crisis version sundipped for 15,000 years) is not more powerful than the Pre-crisis Superman with the Sword of Truth, however it's not Superman's power alone, it's the Sword's.
The only Superman who would even have a chance is E1 Superman with the Sword of Superman.
Superman Prime, who is the post CoIE Superman, thousands of years in the future, with 100 GL Rings and the Spear of Destiny would still lose.
