When I first started I didn't like the way a pick felt in my hands. I used just my fingers for probably a year. Then I slowly started to try using a pick and pretty shortly after that began using them exclusively. There's some techniques I picked up from using my fingers, like playing songs that require you to pinch two strings and move between the others fairly quick, that is hard to pull off with a pick, so for that I would prefer fingers, otherwise I think a pick sounds better on pretty much everything else.
BTW a good song for what I mentioned with the fingers is "Landslide" by Fleetwood Mac.
