To be honest, I don't think there'd be much difference between the quality of that Schwinn and the two original cruisers you posted. The two you posted earlier do have the benefit of being from a local bike shop, though. For a cruiser, I don't think there'd be too much to worry about on a Schwinn.
The problem with the big box store bikes isn't necessarily the quality of the bike itself (which, true, probably isn't the best), but it's that a bike at Walmart or Target is probably being assembled by someone who is not a bike expert, and it's just another task that they have in their busy day, so they aren't put together with the greatest care in the world.
