The consensus among most all “skeptics” that I recall including George has been that a better contact between fuse and holder can make a difference.Yes as Ralph also explained, this is correct and gullible buyers of $$$ fuses think it's the change over from this from the standard cheap fuse that's given them the difference.
Also the standard fuse could have had many turn on cycles, and become crusty, hardened and carbonized.
