Depends on the gig. .
Personally, I much prefer playing 4 string basses. But I was up for a gig where it became apparent that much of the guy’s recorded material needed a 5 string. So, I went and got a decent 5 string. There is another project that I’m involved with that will require a 5 string tuned down a whole step for live gigs (if that ever happens), so now I have two 5 strings, one with a 35” scale.
But for most gigs, I will take a 4 string.
