Not sure if you mean legitimate "pre-vet" major or not, but at NCSU (where there is no pre-vet major, but there are tracks within majors), I would have considered it a big advantage. We did have advisors but more importantly to me there are animals the school owns that you work with for undergrad classes (so for example in classes you learn how to palpate cows, or I did sperm penetration assays and blood smears). You can also get jobs working at these animal facilities where you get valuable handling and research experience as well as contact with DVMs/PhDs who work there so you get to know them outside of the classroom. There are also many classes offered that are helpful in vet school that are animal specific, and I know people who went to smaller schools didn't have these opportunities. I understand it makes you 1 out of a million, but I wouldn't have traded my undergrad experience for anything and I honestly think it did an excellent job of preparing me for vet school.
But I am not saying a school needs all of that to be a good experience, nor do I think it's a disadvantage to go to a school without a pre-vet program. I just wouldn't call it a hindrance to go into a pre-vet program, I just think you have to be more conscious of not being a "cookie cutter" pre-vet.
OP to answer your question, there is no rating those programs, they all have things that appeal to different people. If money is truly not a concern for you then you just need to go to a school that fits you. One that has the pre-reqs you need, in an area you like, as well as other classes you're interested in (lots of people decide to no longer go into vet med after they start college). None of us can tell you which will be best for you. And honestly none of them will get you into vet school just by going there, it's all about what and how you do whenever you're wherever you are.
