Personally with DP cables, especially if you're looking for a longer length cable or wanting to push a higher bit rate through it, then you're better off just spending a bit extra and getting a proper VESA certified cable.

Along with that, I've found that fiber based cables tend to be more reliable than the copper ones. I suspect this is because the media conversion causes there to be a cleaner signal at the output since it has to completely recreate it rather than just amplifying it. Leading to better clocking and less rounding of the edges from capacitance of the cable.
