Both the leaks are on par with earlier leaked ones as both the designs are leaked online a few days ago. Maybe these are the two prototype devices, and the device's design is yet to be made final.
In this image though, the OnePlus 5 looks more like the Meizu MX6 with same antenna band lines. The dual camera setup looks more like the Xiaomi's implementation here. But this design looks gorgeous than the other one, which more seems to be a OnePlus 3T.
The OnePlus 5 will go official this summer, and more leaks about the phone will come online ahead of the official launch. Stay tuned for more updates on OnePlus 5.
