Mine at least lets me adjust the upload and download ratio for my plan. I'm currently on 50/20, but I could upgrade my plan and get 100/20, 70/50, or whatever I want. But 50/20 has been plenty for me, and we're getting municipal fiber soon so I'll have more options as well.
AFAIK, cable doesn't offer that, you get 5mbps on pretty much every plan, or you upgrade to some ridiculous tier to get faster upload.
