It's hard to say, because it's such a different operation and different scale. LGA has two 7,000 foot runways, and no CBP (meaning very few long-haul flights are landing there), as well as all the perimeter rules and curfews... listening to LGA ATC feels more like listening to a small quircky airport, at least to me.

So it's hard to make any kind of comparison.

It will be more telling to see how things settled after the construction is finished.
