ROG CPU-Z is just
TechPowerUp CPU-Z with a ROG-themed cosmetic overhaul, yes? Does it add any ROG-specific features or functionality not found in generic GPU-Z?
I like using multiple graphic engines for benchmarking, measuring raw fps while loading the GPU and CPU together can vary a lot from engine to engine and game to game, having a variety of results to compare allows for better performance comparisons/predictions when looking towards untried software. And more online databases to link into with a wider pool of user reports/feedback than any single benchware tool.
Unigine (cinematic or interactive Heaven and Valley environments), the amusing
Catzilla, and dull-plodding-efficient
Cinebench are all pretty good for GPU "stress testing" and judging real-world performance. So are top-heavy games like Crysis, BF, etc.
