The only thing I don't like about the lead came method is stretching the lead itself...I still don't have the hang of it. But I did love using the lead to piece everything together. For some reason, the process was more meditative than copper foil. Then, the mudding process (the "glue" that holds the piece together) is messy, but it works.
For some reason, the whole process feels more organic. Also, you don't have to solder as much, which makes me happy. I'm not usually a perfectionist, but my mediocre soldering of the lines makes me insane.
