The advantage of k3lr's method is that the quality of the soldering of the braid is easy to inspect. I used the tinned braid tubing cutter method many times but still managed to put a connector on that I filled the holes with solder and not connecting to the braid. (It still worked for a couple of years like that BTW). It looked good.
