Perhaps my word choices were not correct, Dmusic and Jauqo.
Why I feel the dynamics are different:
Typically your fingers have a slightly softer attack than a pick (unless you purposely play hard). Unless we're splitting hairs and getting into the material the pick is made of.
Each one of your fingers has a minuscule difference with the consistency (I play with 4 fingers and my pinky is slightly different than my index, when attacking a note, for example), a pick is more uniform with a the attack, more edgier (granted you can make a pick sound less edgier by rolling off the highs).
But also in the sense of really digging in with your fingers, you will not replicate it with a pick, digging in, it will be slightly different.
Ghost notes do have some difference between pick and finger.
But that goes back to the attack difference.
What I'm illustrating, is not to put down picking, hell I do it when needed as well, but there are subtle differences.
Just my .02
