I'm a student at WCVM, and I chose it over UCVM, so my reply is obviously going to be a bit biased, but I will try my best to give a balanced perspective. In all honesty, both schools are accredited by the AVMA and in the end, no matter what each school says about the other, they are both going to produce fine graduates.
UCVM's clinical skills building tour is very impressive. Despite being certain I wanted to go to WCVM, after that tour I was uncertain and thought about choosing UCVM, despite the fact that I wanted to do exclusively small animals once I graduated and UCVM not having a branch for small animals.
You have to think a lot about what you want to do and what learning style fits you best. UCVM does have more hands-on and has more communication and professional skills training. WCVM's aim for our class is to have about 100 hours in communications training by the time we graduate, but that is not as much as what is offered at UCVM and OVC. UCVM also uses a distributed learning system, which includes a lot of travelling. You have to think about whether you would like to travel a lot in fourth year, or have the option of doing occasional externships at WCVM but spend the majority of your rotations at the teaching hospital.
Electives-wise, I do think WCVM has more electives and allows for a more flexible curriculum than UCVM. WCVM's electives start in third year, and you can choose all small animal electives or all large animal electives or a mix of both, and I believe there's other electives that include poultry or fish. In fourth year, you have a few required rotations, but you get a lot of choice, and can again do mostly small animal/large animal/both. Last year, the UCVM dean mentioned that fourth year rotations can have a maximum of 50% small animal.
Last year when I interviewed, the UCVM dean also mentioned a "mandate" for UCVM to do mixed practice and for WCVM to lean towards small animal. This is not true, or if it is, it's not being applied. First year at WCVM has had a slight large animal slant if anything. Their large animal department is very well-developed. I was born and raised in Calgary, and when UCVM started all the rumours were that you should go to UCVM for mixed practice and WCVM for small animal. I carried this notion with me when I started at WCVM, and I have been proven very wrong.
If cost is an issue, UCVM is more expensive. They will offer you a scholarship if you get in, and if you're particularly high-ranking they'll offer even more. For their normal scholarship, tuition would still be more expensive than at WCVM. However, the clinical skills building is new and has a lot of nice technology, and some of the stuff at WCVM is fairly old. UCVM's anatomy lab is definitely nicer.
At the end of the day, both schools will produce fine graduates, and it's up to you to weigh the differences and decide which school you would like the best.
