I really wish some Canadian ATC could
do an exchange tour and see how it's
done at a busy airport in the USA.

They've never heard of this place called
"Oshkosh" or "O'Hare" or "Atlanta" or
any large airport in the northeast.

ATC in Florida impressed me, I think JAX center. Obviously extremely busy airspace, south of Jacksonville. Very busy, very quick and accurate, and very friendly to boot. (just try to imagine how many student pilots in Florida)

Same with DC area controllers. It's tricky airspace, very busy, and they were great with an unfamiliar pilot (me) during challenging weather conditions. Very patient and professional.
