Shunyata Python Helix compared to Taipan Helix

First, I've researched this already but would still like to pose the question -

Anyone familiar with the differences between these cords? I recently picked up a used Python Helix to compare in my system, which is already fitted with Taipan Helixes. It doesn't appear to be a big difference maker. Slightly more resolving with a bit more bottom end response (too much low end response for my taste initially). Questioning the difference in price (used and new) for the Python, but perhaps it needs time to settle in. Maybe the low end response is what people are paying for?

I've found more high frequency response differences between my Taipans, which all have different platings on the AC ends (Nickel, Silver and Copper). These different platings work well when tuning/matching between components.
