What phone/OS are you using right now along with what OS you would like to try?

OnePlus 10 Pro on OxygenOs 13.1

I like it better than stock android, and while it's not perfect I don't dislike it enough to want to switch. OnePlus 1 came with CyanogenMod out of the box which was super fun at the time.

I mainly stick with OP for the 100W fast charging, otherwise I'd be happy to switch to Xiaomi or Huawei for better value
