Your best bet is the OnePlus 6T for sure. Great price and amazing specs. I had the OnePlus 3T before this and only upgraded because tmobile has a 50% off deal with a qualify trade in. I fully expect this to last well past two years. The OnePlus 3T was a champ and even after two years of use it was not slow nor did the batter die fast. As long as OnePlus can keep this kind of quality up for about half the price of the most popular devices, I'll be buying their's forever.
