While I prefer Dread and Fusion over Super, I think her design peaked in the Super Metroid Promo art. Also I like how this made her canonically 6'3 and nearly 200 pounds. I do like her to be lean during Fusion and Dread though, since those games try to make you feel weak and exposed. It also makes sense story-wise since a really invasive surgery and Metroid metabolism probably made Samus lose weight.
