I definitely prefer pickstyle. It irritates me sometimes when some people push things too far and make statements like real bass players don't use a pick. Nevertheless, because of my neck problem I do sometimes have to join the ranks of fingerstyle players. It doesn't much matter one way or another. I don't have Carnegie Hall booked anytime soon anyway.
There is no better or worse, just a certain way in which your groove will be influenced as you mature as either a finger or a pick player. Sure as a pick player myself I gravitated towards pick players as role models - Glenn Hughes, Roger Glover, Jim Lea, Martin Turner, Chris Squire, Alan Lancaster, Gene Simmons, Dennis Dunaway, Bob Daisley, John McCoy, John Gustafson - they are all pick players. But at the same time I marvel at all the rhythmic nuances Neil Murray, Jack Bruce, Trevor Bolder or Gary Thain play(ed) - and that kind of style is derived from having chosen the finger player path.
