For me, at least. I arrived at my bus stop and waited only a few minutes for the bus to come. Stepped on at 8:26, took the F in Jamaica then E and stepped off the 6 train in the Lower East Side at 9:36. Total travel time: 1:10. (Recently, it has been taking a lot longer due to "track improvements" for "Some Manhattan-bound trains run local from 71-Continental Avs to 21 St-Queensbridge" which oddly does not affect the E and does not have any construction lights to show for it.)

On my way home, a R train was arriving right when I stepped onto the concourse/platform and I got on at 4:04. At Union Square, I transferred to an arriving Q train for a quick trip to 34th St, then for the F, which arrived as soon as I walked down the irreparable escalator. Stepped off the train after only 40 minutes! As I finished climbing the stairs out of the station, a bus was already waiting...with another pulling in several seconds later! 22 minutes after I alighted from the train, I stepped off the quick driving bus (when I turned my head to say, "Thank you," to the driver, he said, "You're welcome. Have a nice day," before I could even start.) Total travel time: 1:02! Unbelievable! (It usually takes 1:20, and a lot more waits)
Guess I was lucky today! I just hope I haven't angered the "subway gods."
Also, Second Avenue Sagas has taken a much deeper look at what was and became of the "1939 IND Second System," a plan by the city of New York to expand the subway system by an additional 100 track miles, potentially relieving today's packed subway cars and improving mass transit for everyone. (And potentially discouraging Robert Moses.)
