Just spent a few hours with the new DXO OpticsPro 10 trial. Looked at the older version about a year ago and rejected it for a number of reasons, primarily the price (and discrimination against FF cameras).
The new pricing scheme is certainly more attractive, but at $200 it still has to offer a significant advantage over Photoshop+ACR or Lightroom. I don't see that much advantage. The only advantage I see is in the lens correction functions. That's the main DXO claim to fame, and they probably do the best job of anybody. But it's not that big of a concern to me. I'm satisfied with Photoshop's lens correction. And I'm very impressed with the "Upright" feature in ACR plus the "Adaptive Wide Angle" filter in Photoshop.
With respect to the new "Clearview", I found it does some interesting and attractive things. It's definitely better than the Clarity slider in ACR. However, when I compared DXO Clearview with the Topaz Clarity plugin, it came up short. The DXO Clearview has only one "intensity" control. Topaz Clarity has 7 control levels.
That amount of control requires a longer leanring curve, and can be intimidating for those who want a "one-click" tool. (Although there are several one-click presets in Topaz). But the range of results is far better. I found it easy for Topaz Clarity to duplicate the results of DXO Clearview, but impossible for DXO Clearview to duplicate Topaz Clarity.
If you want to avoid full Photoshop, then DXO OpticsPro may be a good alternative. But if your main goal is local contrast enhancements, like DXO Clearview, look at the much cheaper Topaz Clarity.
