I cant speak to the build quality of Thunderbolt cables made by manufacturers other than belkin or the one Apple sells - both of which have been great. The belkin cable feels a slightly more rigid. As far as Thunderbolt branded cables you can expect to get the speeds and power delivery that’s advertised, just pick the cable that’s right for you. The one I mentioned earlier is certified for up to 40Gbps and 100W power delivery.
