I was more curious about people's upgrading patterns with OnePlus, not so much comparing the 6 to the 6T. Theoretically, the T version will always be an "upgraded" version of the earlier release, but that doesn't necessarily mean that's the model people choose to upgrade to if they upgrade annually. I'm leaning towards staying on the "T cycle" just because it's usually released in season with other top flagships (Note, Pixel, iPhone, etc), and would be more competitive specs-wise with those devices. That's just my opinion though!
