Hi Jay:

I don't believe there is any difference between the "yellow label" Fiamme sewup rims and the "Ergal" ones, except for period of manufacture and label type.

There were yellow label Fiamme non-eyeletted 510-gram clincher rims, however, that were very different from the tubular yellows, which are a true 290-gram rim. (GEL280s don't weigh anything near 280, BTW, but I digress!)

The tubular yellows/Ergals are made from "Ergal" aluminum - 7000 series material. All other sewup rims that I'm aware of from "back then" were made from 6000 series aluminum, a lower-strength material. Ergals resist flat-spotting and "taking a set" much better than any other vintage sewup rim of anywhere near comparable weight, due to the material's higher strength, but they do also fail in fatigue occasionally. This usually, but not always, occurs at high mileage. Rider weight and riding style seems to be involved as well.

We've discussed Ergals pretty much ad nauseam here on CR - I love 'em, some other folks do too, some don't. A general recommendation might be that they're best suited for lighter riders that don't fail bike parts regularly.

Where I'm still taking your cast-off NOS Ergals and "disposing" of them properly!
