I've learned that, when coming to the US from Europe, if I can't get a direct flight, I prefer my change to be in Canada. This way, I can pass immigration on the Canadian airport, while I'm idling between flights anyway. Also, the one time I did it, there was almost no queue (in Toronto).

When I had a connection in Canada, my incoming flight was delayed, the lines were long and I was at risk of missing my connection, so I made the opposite conclusion.
