I had a couple of friends go to SABA. Most matched and are practicing. When they reminisce about times there, the biggest con they all brought up was the remoteness of the island and the lack of amenities, which made life a little challenging. As far as school comparison, SABA is cheaper and class sizes are dramatically smaller compared to AUA. When my friends were there I think their class size was 30-40 (this was about 10 years ago though). From an academic point of view both will get you to your goal, but from a lifestyle perspective AUA definitely takes the edge. Hope this was of some help.
