So I bought every pure copper cable from XINHS, because I don't know how to choose...
The bottom right is kindly gifted by the shop. It appears to be this model:

I've only gone through every cable 2-3 times. Haven't decided which one is my favorite yet. Here are some initial thoughts using my Final B3 and Hugo 2.
1. Build quality is indeed insane for the price.
2. I'm glad the gifted pure silver cable (
https://www.aliexpress.com/item/3256801687782696.html) is my least favorite. Compared to the rest, the midrange is noticeably brighter, even though it does not lack bass. Notes lack weight. Not my style.
3. All cables sound better than my current Final C112 cable (which is superior to B3's stock cable). Compared to them, C112 lacks bass, and its treble sounds glaring, typical for thin-gauge cable. All of them sound different.
4. The second in the bottom row (
https://www.aliexpress.com/item/3256802650980379.html) has the best midrange of the bunch. Extremely smooth and warm. It appears to be the best selling pure copper cable from the AE shop, and deservingly so. It doesn't have the best top and bottom end extension, which likely contributed to the perception of midrange smoothness.
5. The only ones I dislike are the second and the third in the top row (
https://www.aliexpress.com/item/3256803106115219.html,
https://www.aliexpress.com/item/3256801551947168.html). The second sound noticeably brighter than the rest. The third lacks bass compared to the rest, and has treble glare issue like my C112.
6. The top left (
https://www.aliexpress.com/item/3256802141543601.html) is the most expensive of the bunch. I haven't decided if it is my favorite yet, but it is by far the least flexible and heaviest cable. I feel positive about the overall warmth of this cable.
7. The most portable cable are the top right (
https://www.aliexpress.com/item/3256802791450588.html) and the second in the bottom row (
https://www.aliexpress.com/item/3256802650980379.html). They are the most flexible, easiest to wrap into small circle.
8. The third in the bottom row (
https://www.aliexpress.com/item/3256802131451835.html) has some practical issue. This cable is thick but soft and flexible, don't get me wrong, but the surface of this cable is extremely grippy. Really all three bright-bronze-color cables have this grippy surface, but the fact that this particular cable has the flattest grippy surface (due to each core's thickness) makes it difficult to be taken in and out of pocket. I suspect once it collects more dust it'll be better.
