I've been loving this watch since I first put it on. From what I've read, the Samsung Galaxy watch is considered better, but you need an additional wireless plan, and I didn't want that. The Pixel Watch 2 has a bluetooth/wifi option and that is good enough for me. I already had a Pixel 8, so it works seamlessly with my phone.
I also really like how customizable the phone is. There are lots of watch face options and you can even further customize each watch face. There are also downloadable watch face apps for even more options. I have not explored this too much beyond what is included on the watch. There are lots of accessories available to customize the look of the watch. It comes with a basic silicon strap. It's fine, but you can find different colors and styles of bands and cases.
I have two main complaints...
1) Battery Life - You have to charge it once a day on average. I like using it to track my sleep, so I need to charge it during the day. That being said, it charges quickly. I've gotten in the habit of charging it in the morning when I sit down to start my work day.
2) Charging Cable - It has a special, unique charging cable. It doesn't plug in, it uses a magnet to attach. It's always annoying having special cables for charging. It is also a different charging cable/mechanism than the previous model.
Additional Concerns... You need to get a protective case. It's a watch, you will bump it into stuff, drop it, etc. Just a screen protector will not cut it. The curved body means a film protector will come off more easily. There are plenty of cheap options for protective cases available, though.
