I have the P4XL and 11 Pro Max and switch back and forth. The P4XL face unlock is faster and takes me straight to my homescreen. No swiping required. Sometimes i can just glance at the Pixel and it unlocks! It is amazing. Then combined with Motionsense the display is on while i am reaching to pick up the Pixel.Curious to what makes you think it is the best in the business ? Personal experience ? Having had the Pixel 4 and owning the iPhone 11 Pro I think they are as equal as they can be. The speed difference is so little that should not make a difference to anyone. I tested them over and over again and I never could see a difference in how fast they unlocked compared to each other.
Don't get me wrong...I love my iPhone and it is my daily driver. But imho Googles facial unlock is better than Apple's right now.
