Quality of education, facilities, and training aren't things that you can infer from rankings.
Quality of education is pretty much the same wherever you go, and the quality of the student going in determines the outcome more than what school that student goes to anyway. If you're really worried about that, then look up national board pass rates over the past several years for each school you're interested in. You'll see that for the most part, pass rates are in the high 90's for all schools (and the few students who don't pass tend to do so because of personal problems). The only thing that will make much of a difference in this department is the teaching style the school has. If you just want a traditional Didactic teaching style, it really doesn't matter which schools of this type you go to. If you don't, then look up schools that have alternative teaching styles. If anything, I would personally choose the schools that give you the most clinical rotation time in your third and fourth years when you know enough to have case responsibilities. Maybe you'll prefer to have more clinics time during your first and second years, and a few schools aim to do just that. Also think about whether you want to go to a school that allows you to track or not. It won't change the curriculum much for your first two years since you still need to pass boards, but it might matter big time once you're in clinics.
Facilities and training are things you'll have to really research on your own if they're important to you. If pretty lecture halls matter to you, then go visit them or ask current students about them. If new and shiny hospital wings matter to you, do the same. But make sure you ask about specific things and not just about "the hospital," and make sure to ask about it in comparison to other vet schools. Not so much compared to specific schools, but more in terms of how does this school compare to all the others type thing. Ask specifics about the general field you want to go into, because if you're a small animal person, it won't matter as much how great the equine hospital is, if the small animal hospital is old and has the smallest caseload in the country. Which brings me to an important point, hospital caseload matters waaaaay more than what shiny equipment the hospital has (esp because the latest coolest equipment won't matter to students... since they're either not allowed to touch them, or they're for referral procedures that don't matter to a majority of practitioners). If you're really interested in a specific field like nutrition or behavior that tend not to be core clinical rotations in many schools, it might be a good idea to see if the teaching hospital has a department with clinicians in that field. If they don't, you can always spend elective time elsewhere, but then you might want to ask how many weeks your school allows for external rotations.
Definitely try to get the opinions of multiple new grads and fourth years from each school, because they will know how the whole curriculum fits together to produce the resulting clinician. If you ask first-second years they can tell you how awesome their anatomy professors are, or how cool it is that they get so much hands on time with animals, or whatever, but how much these things will matter will change a ton as you progress through the curriculum and begin to realize what thins you wish you had more of, what was a waste of time, and what things you wish you are really happy you've had. This is not to say that opinions of underclassmen don't matter, because they can be very important. But my point is more to make sure you get a balanced view esp with those who have gone through clinics, because most student reps available at vet schools are the first and second years and it's really hard at that stage to understand how the entire vet school experience comes together.
As for employment, I wouldn't worry too much about which vet school to go to. If anything, your best bet is prob to go to school at the state where you're likely to seek employment, since many clinic owners are going to be alums of the same school and will more likely than not have a good bias. Only thing is, if you want to be a food animal vet in beef country or something, don't go to schools that don't have a good caseload with beef cattle unless you're willing to spend a ton of effort getting that experience and advocating for yourself.
