Taking hwy 92 around Atlanta?

Hello, I'm driving from St.Louis Mo. to Clearwater Fl. via I-75. From what I've heard, driving through Atl is worse then driving through Houston Tx.(where I used to live) This is why I thought about taking Hwy 92 from Cartersvile to Fayetteville. The only down side is this adds about a hour to my driving time. so I was wondering if driving through Atl on I-75 is as bad as people make it out to be? And if so Is there a quicker way around Atl other then 92?
