Hmm... Gorgon would probably have him beat. If multiple of them saw him at a time, he may not be able to destroy them fast enough. Plus, Goku isn't exactly a problem solver, nor is he known well for his stealth capabilities. The puzzle of getting out of the maze may take him some time. Unless of course he knew the exact location of Atheon. He would just teleport there in half a second, no big deal. I assume he could sense atheons power. So yeah, he would probably just skip gorgons. And at Atheon, any time he gets teleported, Goku could just teleport right back. Though I wonder what would happen with the oracles/relic? This is a tough one indeed.....
