In sum:
Both cables are cheap and better keep both.
Godiag J2534/VNCI J2534 also works in ELM mode. It is compatible with ELM apps. Openport does not. But Openport comes with ECUFlash for Subaru and Mitsubishi cars.
Both cables will not perform any programming with it. If you need something just to see codes than this will work fine but it is not the universal tool for performing any functions. Both cables can only be used as J2534 devices, they cannot emulator OEM software.
If need a j2534 device that will also emulate original factory software, go for vxdiag instead.
