Both G and I voted for making it Atlanta-centric, and my preference was for a city-focused name, rather than a mascot-focused name. The latter always makes me feel like it's a team that could be anywhere, and I am more accustomed to supporting the team of your city. My vote was for FC Atlanta.
I almost won.
I bring you the unveiling of Atlanta United FC.
Atlanta started as a city called Terminus, as it was a railroad end and then change point. It remains a transit city, with the busiest airport in the world and a moving and diverse population. Thus they justified the name. I'll take it.
