Ares is being seriously underestimated here, hes gone toe to toe with herc.
Aside from that, lets take both Herc and Ares in their full god forms.
If any of you are unfamiliar with Ares in full god form, he had a run about a year ago, where he soloed an entire pantheon of gods.
Was the asian death god like ones.
Well, the general rule is that we are using the current form of a character, which is sad since Ares has been dumped on. He looked so promising in his Mighty Avengers debut, but hasnt been written up to snuff. Same applies to Sentry, but thats another topic altogether. Marvel needs to get on that writing crew's ass.
Anyway, Maestro is a insanely strong version of the Hulk, he should be able to take this.
