I personally like either style of zombie but with how annoying they currently are to kill and the fact that we have a pvp system as well, I think the "original romero concept" with walking(?) zombies would be much more appropriate and that is something they can implement on a whim, with a little programming.. I think that would be the current perfect balance between annoyance, immersion and contribute to pvp as well. When a walking zombie is aggroed, that player may not be aware until too late - as another player has seen from a distance that it is walking somewhere. not knowing exactly where it is going without some longer observation is much better than the current in which they run straight to the player within a matter of seconds and spoil (in many cases) a player's good use of concealment (due to the zombies being so laser-eyed in their acquisition)...
