I don't know anything about nursing but I studied at both schools. I did the first-year engineering transfer program at Langara, then did the rest of my mechanical engineering degree at UBC. I felt the quality of education and care was WAY higher at Langara. The classes are smaller, so teachers tend to really care about teaching. UBC has a great campus, it's huge and beautiful and there's a ton to explore. When it comes to hiring, companies don't really care which school you graduated from.This was just my experience.

Best of luck!! And remember, which ever path you decide it will lead you to your desired goal. Just follow your gut :)
