This question comes up every once in a while. Once I got used to a 5-string, I couldn't think of a reason to go back to a 4-string. The ability to have more hand position choices playing in keys (especially F down to D) is well worth the extra string. I can always stick to the top 4 strings if I need to for some reason, and then the B string just makes a nice thumb rest. In fact, if I switch from active to passive and I have a bass equivalent to any traditional, passive 4-stringer.
I've purchased 4-bangers here and there, but always end up selling them. Why have fewer choices on fingerings and hand positions?
If the 4 is more comfortable, great. Use it. But a "trend" of using this or that is of no relevance to me. I don't like 6-stringers but think it's cool if others like it.
