Taza is 16.3% Ni and I think the Germanium content is extremely high at 0.2% or thereabouts. Pretty unusual iron.

Did not look it up. I was not sure; relied on my sometimes defective memory, and for some reason I thought that Taza was 6 %. But if it is the other way around 16% plus, then the difference is still evident with the right testing. And I don't think an etch pattern will be the same.
Glorieta is as I read somewhere a tad under 10%... but that probably was from a small piece and variations can exist in this meteorite.
A high Ni content could explain why both meteorites still have fusion crust.
Anyway thanks for the correction.

    Not quite sure about this. Taza is described
    as very rich in nickel (over 16%), whereas
    you find 11.92 % Ni for Glorieta in Buchwald.
