This post was inspired by a post from NormanLikesPJO, so like theirs.
I think Camp Jupiter is better than Camp Half-Blood. They have more intense training. And they're more organized.
Camp Half-Blood also doesn't accept Legacies, which gave a lot of campers to Camp Jupiter, further strengthening them.
Also, they have more supplies and tools in Camp Jupiter, so they're prepared for attacks. And the Romans were always good fighters, which is evident in the Camp.
Camp Half-Blood didn't even let in Minor Gods until after the Titan War, so they didn't have many people, and in the winter, they'd most likely be absolutely destroyed, but Apollo helped defeat the Statue attack.
The Romans were a little more focused on Weaponry than on Powers, so they didn't even use the same system as Camp Half-Blood. Having Ranks is smart, as they know who's stronger and who's weaker. So if they have a really powerful giant, just send the First Cohort.
Instead of Capture the Flag, they have War Games, which are more intense and training. Like, Capture the Flag would teach you thieving skills and teamwork, but from what we've seen, there's a lot of all out fighting, which is where War Games come in.
The only problem was that they're dangerous, but The Camp is the kind of place where, "The weak don't survive."
And Lupa teaches the Campers skills, so they're trained before even joining the camp.
Imperial Gold is really strong, and the Romans like one-shots. They stab instead of slash, so they always kill their enemies. But no offense to the CHB fans and Greeks. Zeus, don't kill me.
But Jupiter's more calm, so he wouldn't.
