I would get the Nishiki for the mere fact that Schwinn looks like it might have a lot of corrosion on the rims and the decals are in bad shape. It's only cosmetic, but I would feel the need to factor in the cost of a new wheelset before I would be happy with it and I'd have to remove or replace the decals.
The "bent rim" on the Nishiki is probably just out of true.
Watch out for bent forks though. You can't tell from the pictures of either if the fork is bent or not.
