The short answer
AMD RX 7900 XT can run 4 models that NVIDIA RTX 4080 SUPER can't fit in VRAM — mostly the larger models. For the 23 models both can handle, speeds are similar. If you want headroom for bigger models, AMD RX 7900 XT is the clear choice.
4 models B runs, A can't
11 models A is 20%+ faster
12 equal (both run, <20% diff)
27 too large for either
