I will add that take my opinion on that with a grain of salt. I don't care for 5 string basses for me, so that may completely bias my opinion. My main band tunes to C standard. Plenty of people have suggested I use a 5, but my 35" scale 4 string Spector Euro (about to have a second one that is getting refinished) and my Dingwall ABZ-4 are just what I personally like to play for downtuned music. If I had a gig where I needed a low B, I'd probably just tune one of them BEAD.
Its what your comfortable on right???
I often wish I went to a 4 and stayed there.
