I'm typing this from a 6t. No complaints with it so far, it's far enough in that I need to replace the battery but that's to be expected. The 6gb of ram has proved to be really helpful in ensuring that things always work and the dual sim has let me combine the work and personal phones into one.
I know it's long in the tooth so if anyone has some recommendations for a replacement that has dual sim and doesn't cost an arm and a leg please reply!
