Are all Visa cards the same for insurance/fraud detection?

I’m having a hard time dealing with my bank disputing a charge made to my credit card, (which is quite different than my dealings with them in the old days). I’m wondering if I switch banks/cards if I’d have better luck in the future if I have to dispute something. Or are the rules & standards all the same no matter what bank card I get? Is it the bank that resolves disputes, or is it Visa?
