I'd skip both. There are better bikes to be found at yard sales, etc, for the same cost.

However, if the color or headbadge or condition is right, just go for it.

I try to find older Shoguns, early 80's: no braze-ons, Tange frame, generally great paint condition (Panasonic-made).
They can usually take 27's or 700's, nutted or recessed calipers (mild modifications) and have cool headbadges.
The more "standard" bb, head tube, and seat tube sizes make the build a lot easier, in many cases.
