The answer here depends on your goals. Do you compete or do you want to? There will be a big difference between competition-focused gyms and regular gyms that have some PL equipment.
Out of Alders' list, Coffee's and NGBB would be my choices, but both are geared toward competitive lifting, so if that's not your thing and you just want a place to train hard there are probably better choices. I'm not a big fan of Quest. There is also Body By George in Loganville ran by legendary PL'er George Herring and Iron Beast Barbell in Gainesville. Both of those gyms have lifters competing at the international level and both host meets occasionally. Both of these emphasize competition but are big enough to accommodate other interest too, like bodybuilding, crossfit, etc.
If you are into the non-competitive side of lifting, I won't be of much use. Hope that helps.
