I guess I'm on the other side of the coin since I have tried several times to like Lightroom and just can't do it. Admittedly I haven't used it that much since every time I get annoyed again. I think the main thing is that I do not want a catalog utility and Lightroom will not allow one to get around the fact that a big portion of its reason for being is related to that. Regardless, I don't care for it even though I have a copy in a box I've never even opened.
I personally feel that as an editor Corel Aftershot is one of the best-priced alternatives on the market. Formerly the $200 product Bibble 5 it is now priced at $59.99 and rebranded by Corel. It is a true EDITOR, not a catalog utility or an add-on, but a standalone editor and capable of some outstanding work.
I also occasionally use Corel Paintshop Pro X4 (although I think they may be on X5 or X6 or something now). A somewhat lightweight clone of Photoshop it is a highly capable pixel-level editor that costs about 1/10 as much and for photography works about 90% as well.
DxO Optics Pro is on Version 8 now and I only have version 7 so I don't know much about the later version. I use version 7 quite a bit for some functions, specifically distortion corrections and some other functionality that other software doesn't do quite as well. My biggest complaint with V7 (which might have been resolved in V8) is a horrendously slow startup time.
I also have Photoshop CS6. I started using Photoshop years ago when it was version 3, I think, and used it extensively at the time. I got away from it for a number of years though so I don't profess to be proficient with it because I don't really care for it. In my opinion Photoshop makes it very difficult to do some things that should be very simple so I tend to avoid it unless there's no other way for me to get something done. It is considered by many to be the gold standard of editors though, and for the price tag it carries it most assuredly should be gold plated.
My personal editor of choice is Nikon Capture NX2. I've been using it for several years, it does 90% of what I want done to a photograph very quickly, it does it very well, and I will continue to use it. As outlined above, I do have other software and I do know how to use it, so I use Capture NX2 because it is what I prefer to use and not because it's all I have. I like the way it works, and for my workflow it works exceedingly well. From my understanding it does not work as well with other cameras, but since I shoot with Nikon bodies that isn't an issue for me.
There are also some freeware alternatives such as Gimp however I haven't used them. Suffice to say that there is something available for everyone though.
