If you serve the song, you're a good player. Period.
You don't have to play 100 notes each measure. You don't have to slap. You don't have to "play out" and toss around inversions.
Sometimes the best bass player is one who locks with the kick, stays in the pocket, and grooves. If that means pounding quarter notes, then that's good.
I think some bass players really wish they were guitar players. There are very few "showboat" bass players. We could probably count them on two hands. Flea, Les Claypool, Billy Sheehan, Victor Wooten, etc. Like Victor himself told me once, "Stop trying to play like me...there are only two bands in the world who need a player like me and I'm in both of them". He's spot on.
