One Plus. As the owner of One Plus 5, I can say that I am satisfied with everything - nothing slows down, the battery lasts for two days, the garbage from the manufacturer is set to a minimum and it is easily removed. One of the key points of the One Plus policy is that unlocking the "root" and installing the "left" firmware does not turn the manufacturer's warranty into a pumpkin. Yes, it is more than a year old, it is "old" by the standards of iPhone manufacturers, but it’s time for thoughts change "has never been - copes with all tasks easily and naturally. Of the shortcomings, it is too big for my taste (screen 5.5), as an alternative I considered Xiaomi mi6 (screen 5.15), but Xiaomi does not support LTE in the USA.
Yes, and all this splendor is for sane money (~ $ 440 at the time of release in 2017).
Apple, Samsung - they have earned a good name for themselves and it's not just that, as they do it with high quality and for people! Not to make money!
