It's always been easy for me, too. I recently got a Nexus card which makes it so I don't even have to talk to a real person when arriving in Canada (at least via air). Literally just two questions in a kiosk and hand someone a receipt. Of course that means the governments of Canada and the US did a background check and recorded my fingerprints and retinas, but I'm fine with that, personally.
I have global entry and feel the same. On the application they didn't ask for anything they didn't already have so it wasn't a big deal. Well worth it considering the included pre check.
