When I ran both yesterday with my ~210MS with 81ML, I got 850k/sh while breaking even on Hero Fortress and 600k/sh with 75k/sh profits on Minos (Green PoCs goes for 5k each). I think I had some loot luck on Minos though, I used to do around 50k/sh profits 15 levels ago when I ran it more often.
In my experience it's much more likely that you'll run into other people in the spawn in Hero Fortress, but in Oramond there's lots of high level manual players who might try to fuck with you if they notice that you're a bot while you're depositing.
