Depends on your perspective. I've never flown the 757/767, would sure love to, but the newer 737-800 cockpits are much quieter than the -400 or older -700, -900s that we still fly. The overhead windows are gone, The standby attitude/flight instruments are gone, replaced by a video screen without the noisy vibrator, the rain wipers are quiet and the A/C fans are much quieter. I'm very happy to take off my headset for those long cruise portions of cross country or trans pacific flights.

I'm sure the MAX will be better still.

As much as I wish the order had been for 787s, I am happy I will end my career flying new airplanes.
