Fabrication matters

Flat iron depends on correct removal of the top blade's central seam. Skirt labels and trimming vary. Confirm what is actually in the package before treating the names as guarantees.

Why score alone is not enough

Both sit in the same ordinal budget tier, so meal and method drive the ranking. The model favors flat iron for a steak dinner and skirt for a sliced filling.

Decision rule

Buy the shape and fiber pattern that fit the serving plan. Neither score includes a local sale price, marinade preference, or individual cooking skill.
