I've found that NAPA's winter blade/frame replacements work better than the oem wiper blade frames with replaceable blades. The rubber seems to be a higher quality and the plastic encasing the frame keeps snow out from between the flex frame. They fit oem arms without any adapters for a clean look.
NAPA sells their winter blades by application. No need to consult app books at the wiper blade section. Just give the parts sellers the app. I think they cost around $12 each. One of the few, cheap options that I've found.

It snows in Atlanta, right?
