I'm one of those who cannot use a pick, have never even tried, mainly because I think the sound you get from a pick is crap, basically. I do use one on one song, Ace iof Spades, because it really, really wouldn't be right without one, and in all honesty, I could not do it justice with my fingers.
Having said all that, one of my favourite bassmen is Joe Osborn, who sounds great despite doing it ALL wrong. Pick, flats, Jazz Bass. All wrong. But his lines are sublime, and I love a great deal of the Carpenters music for that reason.
But I have met him some of the way toward the middle - I only play flats now!
As an example of why I hate, hate, HATE the technique, I refer you to 'Let's Go to San Francisco' by The Flowerpot Men. Aaaaaaarrrrrgggghhhh! And it was played, horrifyingly, by none other that John Paul Jones!
I rest my case, in my case.
However, the point is that you play with what you play with, whatever works for you. No different from one's taste in basses.
I hate fancy coffee-table basses, but if that's your definition of a good instrument, so be it. And so on...
