If I understand it right (from almost nothing other than the comment in this L&L article), the argument against the surprise rules is that players don't like the -20 initiative having effect right through the encounter. I don't understand that at all. Initiative rolls only really make any difference at all during the first round of combat; once combat gets into swing, everyone essentially goes both before *and* after everyone else! And if it so important to you, you can move about the initiative track by readying an action.
You must not have many games you play if one rule can prevent you playing them.
