I have DxO (v8) and used to use it a lot. Again, the ability to batch process a whole group of photos is nice. You can set it up to output into a variety of formats. And, the lens corrections are well done.
But (in all fairness), I've never taken the time to truly master using DxO. Some on these forums use it and use it well. I've found LR more intuitive and quicker (for me) and hence I think I get better output. I think it is a matter of personal choice.
No matter what you choose, work with it and you will be fine.
Technically speaking, the quality of the JPEG compression affects the final pixel count as does the final desired size of the picture. This really does not matter so much for reducing a count to let a photo fit onto a web site like CR but cn affect the look of the final product should you want a big reproduction for yourself. There were some pretty startling examples of this in a blog talking about compression (google "why facebook photos look so bad" to see some of this and other examples). And the amount of information stored is somewhat fluid as well. If, for example, you do a lot of editing especially with layers in PS, the final file is often larger than the original. So what you see on FB or Smugmug is not always 100% the same as what I have on my HDD or on a quality print.
Anyway, that's my understanding of this which may not be totally accurate but works in my head. Maybe some others can add to this.
