Consider the OnePlus 7T
While the revised OnePlus 7T Pro isn't available in the US (only the cheaper 7T model) they're both still excellent phones worth buying. You can import one to the US, or even get T-Mobile's OnePlus 7T Pro 5G.
On October 10th of 2019, the company announced a slightly improved OnePlus 7T Pro with a bigger battery, faster Snapdragon 855+ processor, faster charging and the latest Android 10 software. And while it isn't a huge change over the model from earlier in the year, it is newer, and a great phone for those that don't want to wait until several more months for a new phone.
If you can't wait but love OnePlus, the 7T and 7T Pro are great options right now and will be for at least the first half of 2020.
