The transient response doesn’t look bad if you look at the registered deviations. Nonetheless, the low nominal voltage of the 3.3V rail and the above 6% deviation in both tests don’t help it keep its level above 3.14V, the lowest limit. Don’t expect a good or even decent transient response by a dirt-cheap PSU.

In the pro and cons section you mention that it has both high build quality and low build quality. which one is it?
I left an error on purpose to see who would notice 😀
Bad build quality
