Which is better for a wide face?

The Oakley Airdrop. Its 57 mm lens is a large fit, while the Walmart frame is a medium 55 mm.

Which frame is lighter?

The Walmart FM17197, if the titanium claim holds. Titanium is lighter than the plastic Oakley uses.

The Walmart frame's metal hinge and titanium build should hold up better over years. The Oakley's plastic frame is durable but flexes more.

Is the Oakley worth stepping up to?

Yes if you want a large fit, color choice and lens options. The Walmart frame is the pick if you want browline style and a case.

Do both come with a case?

The Walmart frame lists a case included. The Oakley listing does not state one.
