Nah, my moneys on atheon. Sure goku has power but he doesn't know all the aspects of it nor does he know anything about the destiny universe and his biggest weakness is his mouth. He never rushes straight in for the kill and he always attempts to talk to his new enemy or taunts depending on how high powered up he is and all his abilities take time. I don't care what he can do I care about what he does and has done. Atheon teleports him he's done, he has no way back cause no one is on the portal to open it. Plus atheon teleports you to the past or future so even if he tried to instant transmission himself back atheon won't be there. He can try to "rip a hole in the dimension around him" but there's an infinite number of times and instances that atheon could be in let alone for him to get back. He doesn't know any of the mechanics on the other side or anything about oracles or the relic so odds are he'd be blind too. Most of gokus strongest attacks are made from borrowed energy that also takes time to collect. And since he doesn't steal energy that's a big tick against him. Sure he's strong and he'd get far, but not knowing weakness, crotas sword, auras, etc be wouldn't be able to harm certain creatures. TLDR He's not smart enough to figure it out on his own, (plus no one is there to guide him on what to do) nor gung ho enough to immediately take out an enemy soooooooo no. Goku wouldn't win.

LOL goku can teleport anywhere he wants

Place yes, time no.

Technically Crota and Oryx are gods also.

And so is dende who dies to yamcha

Just because destiny calls them gods,it doesn't make them that. The worms of akka were closer to being the gods themselves,as without them oryx is just an illusionist. The fact that the worms are Oryx's undoing proves he wasn't worthy of godlike status.

They don't have power like Goku and Bills.

They're also dead

So are all the guardians, yet they're still running around just fine.
