I can only speak for the Mate 9. I love it! Besides the cool hardware, specs, superb battery, the software is pretty cool too, lots of nice touches. For one thing it has a great swipe down to search feature similar to the iPhone's spotlight search. Also it has a really cool feature that lets you use some limited functions on the locked home screen like the flashlight and a calculator. Also you can get a cool screen saver/ newsfeed on the lock screen that is suprisingly good!
