I like 10 much more than 9. really like the button for the control panel, makes a lot of sense in use. i use the flashlight a lot, change focus & silence pretty frequently. if you have an ultra, the new modular face is great. i almost never change faces but it’s still pretty easy. just press & hold for a second. the stacks feature is a bit overrated at the moment.
battery life is = 9, for me at least

to be honest, i’m surprised by all the hate. not that big of a deal really.
