WW can't fight superman either. Getting overpowered by him. And one or two shotted by him in most battles doesn't mean she can fight him. It means she is totally outclassed by him. and her skills don't make a difference at all. So in that sense, spiderman can fight superman too.
None of what you said makes priscilla a better villain for WW. Since she is even less of a physical threat to WW than Barbra. Barbra not only matched WW in Perez run first battle. She overpowered WW in WW anual 1995. And even if she was only equal in strength to early Post Crisis WW, that already makes Cheetah stronger than spiderman anyway. And she doesn't even need to be on par with WW in strength to beat spiderman. Because unlike the likes of Rihno, Cheetah has super speed. Greater super speed than spiderman by a very good margin. Also zoom never gave her any amp. He taught her how to use her own power by helping her to remove her mental block. He literally said her speed being based on magic, has no limit to how much it can grow. Cheetah's speed was still being compared to WW and even Flash in the next runs of post Crisis and new 52 as well. So super strength aside. A properly writen Cheetah should be too fast for spiderman to handle. If she can blitz WW, Superman, move behind Supergirl without Supergirl noticing her, tag Flash etc. Then She can cut spiderman to pieces before he could react. Unless you have pis writin taking away her super speed completely. This is the same way that characters like Flash can be a threat to the likes of Superman and Wonder Woman, without having their physical stats. And even if Cheetah can survive just a couple of blows from a serious WW, that is more than enough to take hits from a far weaker opponent like spiderman.
