I've worked with many Ross grads, and their medicine has always been good. I haven't met an SGU grad yet.
From what I understand, if you mess up in school grade-wise at Ross, they have no qualms kicking you out, even if it's your last semester there. I hear it's alot of "tough love". Perhaps the people I heard about were true party people (at least one that I heard was kicked), so take that with a grain of salt.
The other thing that I've heard about Ross is the fact that the islanders are not friendly to Americans. I've heard some awful stories, but then again, that could also be true of nearly anywhere outside the U.S. I've never visited the island myself. Let's put it this way: I wouldn't go running through the woods, or fields, at night and alone no matter WHERE I am!
We had a vet assistant, a guy, who got in and went to Ross (I think it was two years ago now), and came home a week or two later and said he couldn't stay there. He said he was told not to leave his computer in his apartment/room because of break-ins, and not to go out after 6 or 7 pm or such, and not to go anywhere off campus alone. He was freaked out and came home.
Contrast that with, I know a few female vets who went there, and they all survived just fine and practice great medicine. The ladies I know graduated over 3 or 4 years ago, and longer. However, the hoops to jump through are still in place, so going with an already accredited school might be easier if you can.
As far as SGU, I have also heard, second-hand, that the students there now are usually very happy, and the islanders are friendly to the students. That animosity you can find on St. Kitts is not evident in Grenada supposedly. They also have on-campus housing (does Ross now too?) but no pets allowed.
There's a yahoo users group for SGU. I'd recommend it. Yes, a school representative is also on the group, but the discussions are candid.
Everything you'll hear about how hard it is or expensive to ship or bring items to Ross are more than likely true. I've heard crazy stories about the -monthly- or less frequently than that, runs to McDonald's in Puerto Rico and such. You need to like seafood! Get ready to eat lotsa fish! It's similar with SGU too. If you require the comforts of home, i.e., the U.S., with refrigerated milk at the store, and are used to eating beef and /or chicken all the time, it may be a rough transition. And of course, since you're on an island, and nearly everything is imported, things are $$.
I do know that if you take a short trip to SGU and later accept admission to the school, they reimburse you for airfare and hotel, as long as you booked the trip through SGU's approved travel agent(s). Contact SGU or get on their yahoo user group to learn more.
Hope this helps. SGU was potentially a Plan B for me. My main problem with leaving the U.S. was my five pets, of which at least four need to come with me, wherever I go. I also attended an SGU open house last year.
