When you're the leader, you don't have to follow.
It's a breeze getting in to the States - where are you going? What is the purpose of your visit?How much of a hassle is Customs coming and going? Which way is easier?
I've only been through customs once (twice) and it was in the wilderness so it was pretty easy as we only had backpacks and canoes on us.. The main thing I remember is having to pay because we were using a Canadian National Forest (Provincial Park) so camping permits and fishing license had to be paid at customs.
Going back is still pretty easy, but you have to declare all your purchases, especially alcohol and tobacco. I find it's a cakewalk if I have my hotel receipt and all purchase receipts tallied and at the ready. Except for once, they've never needed anything other than our passports.
