Macro Lens Help

I'm looking to buy a macro lens for my fuji s5100. I have a couple of choices, however I want to make the best choice when buying a macro. What I'm looking is getting a three peice +1, +2, +4, a one peice +10 lens. or a one peice 4element +10 lens. The last is the one that costs the most. So I figure it was the best, however I have no idea how to judge. My size is 55mm so if there is a better choice let me know. Thanks.

I have a three piece set and a Raynox DCR-250, and most of the time I use the Raynox. I get good results with both.
