No nylon mono is "significantly" better than any other. Some have different characteristics than others. The ones that have the least memory are usually the ones with the smallest diameter, the least abrasion resistance and the most stretch. The larger diameter lines of the same pound test have the least stretch, most memory, and highest abrasion resistance. You have to decide which you are willing to give up to get the performance you want. A simple example is to compare Trilene XL and XT in the same pound test.
