I'm surprised to find myself somewhat disappointed, and preferring my Pixel Watch, though I'm still giving myself some time in case it's just familiarity. But a few things:
* The available watch faces are pretty underwhelming, particularly digital ones. There's only a single one that actually includes the seconds, as far as I can tell. And the only one with lots of complications is Modular, which sticks the time in the corner, and has a big unwieldy complication in the center. My kingdom for Pixel Watch's Utility.
* No watch face store!?
* I can't seem to set up a minimal all-red face for night time, like I had on the Pixel Watch.
* The heart rate complication is just a picture of a heart that I click and it takes me to a widget that measures my heart rate. I had a real time glance on Pixel Watch, right in the complication, always up to date.
* The sleep tracking is weird and confusing. I need to set up schedules and such? On the Pixel Watch, it just tracks my sleep automatically.
* Subjective, but I still like the size and shape (round) of the Pixel Watch more than this Apple Watch, for now.
