Box Hinges: Before or After Finish

What’s everyone’s opinion on when to route/cut the hinge mortises for small boxes?

In the past, with cheap hinges, I’ve always done it before I applied the finish, but I was watching Doug Stowe’s DVD the other night, and he does it after he finishes the box. I’ve got a walnut and birdseye maple box I’m working on, and I’m going to use my first set of Brusso Hinges. I really don’t know how much difference it makes, but I don’t want mess this one up. Your thoughts will be appreciated. Thanks.
