Be careful about taking the test graphs to literally without taking into account the full range and complexity of SRC.
For example, the Weiss shows on one of the graphs that it allows a tiny bit of aliasing which one might think is a defect compared to an alternative that shows no aliasing, but that is intentional. The very low level of the aliasing coupled with the fact that it is at extremely high frequency makes it practically impossible to hear, but you can gain improvements in other areas (like pre-ringing) that can be more objectionable to our ear/brain.
Without understanding the full picture and why a designer may have made an intentional decision to balance tradeoffs for better subjective performance, i.e. better sound, looking at a handful of graphs won't necessarily tell you what the "best" Sample Rate Converter is. Those graphs, however, are an incredible resource, especially when you appreciate what's "under the hood."
