With Touch ID you take the phone out of your pocket, and press the home button once. Unlocked. Doesn't get any faster than that.

I owned a Moto X and used it as my primary phone for about a month. Their software gimmicks grew quite tiresome. I've since sold it and replaced it with a Nexus 5.
Press the home button to wake. Hold your thumb to unlock. It's fast, no doubt. But unlocking the Moto X is faster. Unquestionably. Swipe down once. And you're done.
And Active Display is not a gimmick. It's the best notification feature in mobile today.
