It depends on what you want... better is often a subjective term and depends on your personal preferences.
Ultimately, you will probably have to try different cables out. You can try to select them by reading reviews so you can get an idea of the characteristics of the cables you are considering and whether you think they will be a good fit for you.
One caveat though... there's a lot of cable companies claiming to use "single crystal" copper with ridiculous claims of ultra high purity (8N copper?). AFAIK, only Neotech, Furutech and Oyaide are licensed to produce UPOCC copper and there are unlicensed companies claiming to sell "single crystal" copper and claim to use the patented process to produce it.
And if you do choose a UPOCC copper cable there is one sonic caveat too, it's not as warm and doesn't have the "weight and body" of regular drawn copper wire. But the "weight and body" are distortion and when you get rid of it you end up with more clarity, detail, focus and better dynamics. I'm all for more accuracy personally but some people may not prefer it.
