In general, yes. But different consoles produce slightly different signals. It all depends on what your goal is, since the suite serves a dual purpose: document the platform for comparison against FPGAs and emulation and CRT calibration, amongst others.
Using several will show you how they differ. Some consoels are slightly to teh left, some to teh top, etc.. colors also vary. All try to match the best that particular hardware, and my understanding, allows.
