As I have continued to play with RAW images, and have been continually looking for the best software. Previously I had mentioned that RawTherapee was my favorite RAW editor. Looks like it has been bested by Darktable. Darktable is amazing! I have done a video tutorial/review as well as listed some pros and cons.
Pros: Has many many features. Very easy to use. Pretty interface. Allows batch editing. Allows you to save different editing profiles. Good image browser.
Cons: Not the fastest. Can still be a bit confusing at time (steeper learning curve). Not in the Ubuntu repositories (yet?) This can make it difficult for some to install (though adding the PPA is quite simple).
Conclusion: This program was mentioned to me in a comment and I am grateful it was! I think Darktable has surpassed RawTherapee as my new favorite RAW editor. The interface looks great and is fun to use. It has an incredible amount of features! This is a program you NEED TO TRY if you do RAW editing!
