I usually fly Terminal 1 on United and recently needed to go to T3 on Westjet and it definitely was different. The stop was mandatory at T3, whereas I've always been waved through with carry on (or only told to queue in line when I have a checked bag, usually for less than a minute) except for one time at Terminal 1 where I had a very dour CBP officer asking me 20 questions about the purpose of my trip (wasn't secondary or random though; I saw him question several people similarly before me).
