My rankings for steel 1987, onto which a DA 7400 group to put:
Eddy Merckx Corsa Extra
Panasonic DX6000
Schwinn Paramount - tie - Centurion Ironman

The Merckx and the Paramount are the prettiest, the Ironman only came in two-tones, the DX in a fade, I think.
If I recall, there is a pretty awesome Nishiki of that year, as well.

If you find the right wheels, also a Kestrel but it's not steel.

There are others. I simply know these models. Fuji and Miyata, I'm sure, had offerings right there. Others beg Campagnolo for that era.
