Six Flags over Georgia isn't your 'typical' Six Flags park. It's one of the 3 original Six Flags parks. What a lot of enthusiasts seem to not realize is that SFoG, like SFoT, is not owned by Six Flags Inc. It's owned by a limited partnership and is ran by Six Flags, and the owners have quite a bit of control about how the park is ran.
To say it isn't better than Carowinds, IMO, is completely false. Carowinds is a nice park, but oG has charm, great rides, friendly staff, theming, atmosphere, and is one of the higher regarded regional theme parks. Goliath is the best Beemer hyper I've been on (I think I've hit all but the couple overseas, Diamondback, and Behemoth, and if popularity is any mark, Goliath is rated higher than those).
The park's dark ride, Monster Mansion, is one of the best dark rides out there. The drop ride, Acrophobia, is a thousand times better than Drop Tower, Georgia Scorcher is the best standup, and so much better than Vortex, and I could go on.
Also, the food is decent at this park. Much better than Carowinds.
It's definitely worth an entire day. I suggest going opening weekend in March.
Here are some photos. The park is beautiful, well run, and not to be missed.
