Whenever this question is asked, its the same result as asking Ford, Chevy or Dodge. The only answer comes from you, which one makes you happy. I can tell you the process I went through before selecting pipes for my '07.
Based on information here, I wanted the Freedoms, the new Freedoms, until I saw how butt ugly they are. The previous version will not fit an 07, so it was the new ugly ones, or something else.
I previously used V&H slipons on V&H true duals, and loved them. Gorgeous sound and good torque. This time I went with Rinehart true duals. I like those too.
I have not seen a dyno comparing the V&H ovals and Rineharts on a 110 yet. I have seen a chart for the Rineharts, and I was convinced, that I could live with the amount of tq they put out. The following dyno chart shows Rinehart vs D&D Fatcat on a 2007 CVO 110. Beware making your choice based on 88 or 95 setups. the new motor has a different cam with different characteristics than HD used before, so comparisons with earlier years is apples to oranges.
If you are looking for kick butt performance, then based on the following chart, I would say get the Fatcat and get the falsie for the left side if you don't like the lopsided look. The Fatcats are also cheaper than the Rineharts.

In the end, the only person who has to like the pipes is you.
Have fun,
Chief
