I thought open manager was the best manager out there
From what i know Open manager is out of date and does not look good at all, with Gaia Manager you get a Up to date Manager and it looks good
There are so many Managers and so many payloads it's starting to get NUTS, I hear "or should i say SEE lol" bad comments all the time for Hermes's Payload and bad comments for Open manager, But then again i can't really test anything yet so... really i guess i can't say much
