Well that's debatable, there are people who use every one of those six strings, most are happy with four though (I play a run of the mill Jazz Bass), but have you ever played one? I played a seven string once and it was SUPER fun.
Yeah, I have played a few 6 strings, I found the neck to be to narrow and very uncomfortable. Everything I have ever played could be played on a 4 string, though 5 strings make some of it easier to play. I have absolutely no need for a ERB. Its not really debatable, unless you are playing the metal scene, or some crazy lead bass lines in a fusion band or something, most players have no need for a 6 string bass. Like I said, they are unnecessary for the vast majority of gigs.
