I've had the Tamron AF 70-300 DI SP USD, which makes the case much more here than the Canon. The Canon 55-250 STM but convinces with its sharpness in all focal length ranges especially from 200mm but also including the sharpness and detail is visibly better than the competitors Tamron. Now have both copies had there and did both with and without tripod compared (based Canon EOS 700D). The image stabilization is a bit better but even with me could not convince the Tamron. In addition, the autofocus is fast and silently.
