Yeah, here's why you never see me using fingers on recordings and videos :flex:
I've personally always had the stance of using a pick when I'm playing the bass under distorted metal guitar (I have to specify "metal" because if it was "rock," I would do fingerstyle under distorted guitar) and doing fingerstyle under clean guitar. But I've heard and seen plenty of people play awesome-sounding bass with a pick under clean guitar and fingerstyle under distorted guitar. I mean, finger style working with metal distorted guitar should be obvious since a lot of my favorite fretless bass players play fingerstyle, but still. In my case, I don't play with a pick because I can't play with my fingers. I can actually play with my fingers fine, but when I play bass, I've always felt that for metal distorted guitar, at least when I'm playing bass, it sounds better with a pick (and likewise I've felt that it sounds better fingerstyle when the guitars are clean / acoustic). :shrug:Finger-players who have always played with fingers and nothing else sound absolutely great, and I would never suggest that they play with a pick instead, as it isn't objectively better.
However, when I play bass, I play with a pick, because my finger playing is just too weak to sound as good. It's got less to do with what's optimal for the instrument and more about what's optimal for the player to get the message across. If you're better with a pick, play with a pick.
Having said this, guitarists who choose to play with their fingers out of some misguided notion that it sets them apart and that they prefer the tone (Jared James Nichols, Mark Knopfler, and Richie Kotzen, I'm looking at you) need to quietly fill their pockets with rocks, and get in the fucking sea.
