The new Do Not Disturb setup and Now on Tap.
The Nexus 5X and 6P also support always-listening voice control: Once you've trained your phone to recognize your voice, you can just say "Okay, Google" -- whether the screen is on or off -- and then ask questions or issue commands. It can really come in handy when you're driving or at home, though the option to enable it is strangely buried deep within the system settings. Some sort of prompt following the phone's initial setup procedure would be helpful; as it stands now, I suspect many users won't ever realize the function is available.

Other new touches
Software stuff aside, Android 6.0 enables some significant new hardware-level features that are relevant to both new Nexus devices. First and foremost is the newly added support for USB Type-C, an up-and-coming standard that'll soon be used across all of Android as well as on laptops and even Apple products. It has plenty of advantages over Android's previous micro-USB standard, the most immediately noticeable of which is that you can plug a cable into the phone either way and have it fit (huzzah!).
USB Type-C also creates a more secure physical connection and allows for super fast charging -- 10 minutes on the outlet gets you up to four hours of extra battery life for the Nexus 5X and up to seven hours of power for the 6P. (Neither phone supports wireless charging, however, which is a shame.) You can use one USB Type-C device to charge another, too, which could eventually be a very useful capability to have.
The challenge for now is that the new Nexus phones are among the first devices to support the standard -- so that means you're going to need to stock up on extra chargers and adapters, as your existing ones won't be compatible. The 6P (but not the 5X) comes with one USB-C-to-USB-A cable that'll let you plug the phone into a computer and both phones come with a single USB-C wall charger. But beyond that, it's up to you to get what you need.
