Use what sounds right for the song, but don't go all gear-snob and pretend to hear differences that aren't there. For our album for example, I used two basses across the entire record; a fretted jazz bass and a fretless 6 string. (I guess you could also count the upright I used a bit but whatever)
There is a benefit to staying consistent and limiting the amount of basses you use. Think of all the well-known players, they often stay with their "number one" bass, they have an identifiable sound.
You don't want everything sounding the same too. If the songs are fairly simple, have roughly the same tempo, the album can start sounding like one long song, and changing it up sets a nice change of pace.
TLDR, Use what sounds right, I recommend not using more than 2-3 basses on a record, each one having very different characteristics.
