Those are two rather beautiful images Bernard! Fantastic work! (The blown highlight on her left wrist in the first is a little distracting, however.)
Having experimented, I find myself turning to DxO 10 for problematic files, such as from my 5D days, whose high ISO performance by today's standards is poor. This CR2 from 2007 was badly under-exposed. In 100% view the girl's hair is a mushy mess but that's a limitation of the data in the CR2, not the processor.

Another use for I find for DXO 10 is where clear view can do a good job nice and quickly. As an aside, I'm finding that in the trip back to LR, the color rendering in LR is considerably more subdued.
Meanwhile I still use DPP and LR for plenty of images too. I still maintain nothing touches DPP when it comes to certain lenses like the EF16-35 f/2.8L. And I also still make a lot of use of Topaz, Nik and Piccure+ plugins too.
