Yeah, unlike a lot of other fights there's no decisive speed-advantage and Herc's stronger but not WAY stronger.
But yeah...unless Apollo can amp himself via the sun then I don't see his eyebeams being enough. As far as I remember (maybe someone can prove me wrong...digi?) Apollo's eyebeams are the kind that would harm the Hulk but not take him out, burn Herc a bit but not come close to actually defeating him. In other words, a helpful tool but not something that can actually win it for him.
