I would much rather go through ICE at Dulles where I know that, regardless of how long ICE takes, I'll be home 15 minutes after I leave Customs.
Same here.
And even as an AC-AC international transit passenger at YYZ for say a Europe-Canada-US routing, if I have checked luggage, then I'm frequently worse off with PreClearance than if I just did the whole US CBP process at a US airport instead of at YYZ.
This kind of thing in Europe has the possibility of being an even worse blunder than that which we've witnessed at AUH.
